Who should consider this test?

Level 1 testing is the perfect test for individuals looking to get a baseline assessment of their cardiovascular risk and overall health. This is the ideal test for someone who isn’t sure where to start in their journey to health. Level 1 testing paints a broad picture of one’s health status, allowing a provider to learn where they may need to dig deeper for answers.

Individuals who have the following health conditions or symptoms would benefit from level 1 testing:

  • Coronary artery disease
  • High blood pressure
  • Atrial fibrillation
  • Heart palpitations
  • High cholesterol
  • Frequent fatigue
  • High blood sugar levels
  • Digestive problems
  • Headaches
  • Frequent infections
  • Excess weight
  • Poor circulation
  • Sleeping difficulties

What’s included in this test?

Level one testing combines two separate comprehensive lab tests.

• Lipid profile test: Also called a cholesterol test, this lab measures fat levels in your blood. Understanding your lipid profile can help assess your heart attack or stroke risk.

Like a vehicle, cholesterol is carried throughout the body in lipoprotein particles. So while some people may not have a lot of LDL cholesterol, they might have many small LDL particles. The higher the number of these particles, the more likely they are to invade the artery walls.

Most standard cholesterol testing does not completely reflect the cholesterol-related risk for heart disease. Fortunately, Level 1 testing includes a complete lipid profile that measures cholesterol particle numbers and size.

In addition to the standard measurements of total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides, our lipid testing includes lipoprotein markers such as:

  • Lipoprotein A – Lp(a)
  • Small dense LDL – sdLDL
  • Apolipoproteins – Apo A-1, Apo B, and the Apo B to Apo A-1 ratio

• Inflammatory and oxidative stress markers: Inflammatory marker blood tests detect high inflammation in the body, pointing to an increased risk of heart disease. Evidence suggests that both acute and low-grade inflammation contributes to the stiffening of large arteries, potentially leading to a whole host of heart problems.

Oxidative stress occurs when free radicals in the body go unchecked. Without enough antioxidants, damage by free radicals can promote heart disease and many other unhealthy conditions.

Specific inflammatory and oxidative markers can often help identify possible heart conditions before symptoms develop. Inflammation and oxidative stress markers included in our Level 1 testing:

  • High sensitivity c-reactive protein (hsCRP)
  • Homocysteine
  • Lipoprotein-associated phospholipase A2 (PLAC)
  • Oxidized LDL (ox-LDL)
  • Myeloperoxidase (MPO)

• Advanced thyroid panel: Thyroid function directly affects heart function, cholesterol, and blood vessels. Some individuals who experience cardiac symptoms have a poorly functioning thyroid. An impaired thyroid can also worsen pre-existing cardiac problems.

An overactive thyroid can cause the heart to beat harder and faster and may trigger abnormal heart rhythms. On the other hand, insufficient thyroid hormones can slow the heart, make the arteries less elastic, and trigger high blood pressure.

Since the thyroid has such a significant impact on the rest of the body, it’s essential to have a clear picture of how well it’s working.

While most health practitioners order a basic thyroid test to include thyroid-stimulating hormone (TSH) and thyroid hormones T3 and T4, an advanced panel is necessary to understand how the thyroid is performing. Thyroid measures included in our Level 1 testing:

  • Triiodothyronine (T3)
  • Thyroxine (T4)
  • Free T3
  • Free T4
  • Thyroid-stimulating hormone (TSH)
  • Anti-thyroid peroxidase antibodies (Anti-TPO)
  • Reverse T3
  • Antithyroglobulin (Anti-TG)

• Advanced metabolic panel: A metabolic panel provides information on the body’s fluid balance and how well organs such as the kidneys or liver are working. It also measures electrolytes in your blood, such as calcium, potassium, and sodium.

Electrolytes play a vital role in the healthy functioning of the heart. Conversely, electrolyte imbalances put you at higher risk for abnormal heart rhythms. Labs included in the advanced metabolic panel include:

  • Sodium (Na)
  • Potassium (K)
  • Chloride (Cl)
  • Carbon dioxide (CO2)
  • Blood urea nitrogen (BUN)
  • Creatinine (Cr)
  • Glucose
  • Estimated glomerular filtration rate (eGFR)
  • BUN/Creatinine ratio
  • Calcium (Ca)
  • Albumin (Al)
  • Alanine transaminase (ALT)
  • Aspartate aminotransferase (AST)
  • Total bilirubin
  • Total protein
  • Alkaline Phosphatase
  • Calculated serum osmolality
■ Advanced metabolic panel

• Diabetes panel: Elevated blood glucose levels damage blood vessels and nerves that control the cardiovascular system. Over time, this damage increases the risk of heart disease. Individuals with pre-diabetes or diabetes tend to develop heart disease at a younger age than those with healthy blood sugars.

A diabetes panel will examine blood glucose levels randomly or after fasting. A hemoglobin A1c test estimates blood sugar levels over an extended period. Those with a higher A1c are at an increased risk of heart and vascular issues. Blood tests included with the diabetes panel include:

  • Hemoglobin A1C (HgA1c)
  • Insulin

• Complete blood count panel: A complete blood count (CBC) is a test that examines the cells that make up your blood, including red blood cells, white blood cells, and platelets.

A CBC helps diagnose blood diseases, infections, immune system disorders, anemia, and other medical conditions. Because the underlying mechanism of heart disease is inflammation, results from a CBC can help to determine cardiovascular risks. For example, individuals with high white blood cells are at higher risk for coronary heart disease.

Some disorders identified through a CBC contribute to cardiac symptoms. For example, anemic individuals who do not make enough healthy red blood cells often experience abnormal heartbeats or a fast heart rate. CBC results included in our Level 1 testing include:

  • White blood cells (WBC)
  • Red blood cells (RBC)
  • Hemoglobin (Hgb)
  • Hematocrit (Hct)
  • Mean corpuscular volume (MCV)
  • Mean corpuscular hemoglobin (MCH)
  • Mean corpuscular hemoglobin concentration (MCHC)
  • RDW-SD
  • RDW-CV
  • Platelet count
  • Neutrophil
  • Lymphocytes
  • Monocytes
  • Eosinophils
  • Basophils
  • Immature granulocytes
  • Mean platelet volume (MPV)
  • Nucleated RBC

RBC potassium

Our hearts are constantly working. To function at full capacity, we must provide them with the right balance of nutrients. Nutrient imbalances can play a significant role in the development of heart disease.

Micronutrients are the vitamins and minerals that the body needs to function electrically and chemically. While they are required in small amounts compared to macronutrients, they are an essential indicator of overall health. Labs evaluated in this analysis include:

• Vitamins: Vitamins play a significant role in keeping the heart healthy. But unfortunately, today’s standard American diet contributes to significant vitamin deficiencies.

Many vitamins, such as vitamins A, E, and C, serve as antioxidants, preventing free radical damage in the body. Vitamin B-6, also known as folic acid, works to lower the amino acid homocysteine levels. Elevated levels of homocysteine are associated with unhealthy lipids and heart disease.

Individuals with low vitamin D levels have higher rates of heart disease, stroke, and high blood pressure. Finally, the K vitamins protect against coronary artery disease. K2, in particular, is essential in keeping calcium out of the arteries and in the bones, where it belongs. Vitamins examined in Level 1 testing include:

  • Vitamin A
  • B vitamins
  • Vitamin C
  • Vitamin D3
  • Vitamin D, 25-OH
  • Vitamin E
  • Vitamin K1
  • Vitamin K2
  • Folate

• Minerals and metabolites: Minerals refer to nutrients required to keep our hearts healthy and functioning properly. The cardiac muscle depends on specific minerals for proper contraction and relaxation. Adequate heart rhythm depends on the appropriate dietary intake of minerals.

Minerals such as calcium and magnesium play an integral role in proper heart function. For example, magnesium is the gatekeeper that allows calcium into the heart muscle to cause contraction. It also aids calcium out of the cell. Without adequate magnesium levels, calcium overwhelms the cell and can lead to chest pain and heart attack.

Magnesium is also essential in helping Vitamin D work in the body, thus lowering blood pressure. Without magnesium, vitamin D is unable to turn into its active form.  The most crucial minerals for heart health include magnesium, potassium, and calcium. Other minerals examined with Level 1 testing include:

  • Calcium (Ca)
  • Manganese (Mn)
  • Sodium (Na)
  • Potassium (K)
  • Zinc (Zn)
  • Copper (Cu)
  • Chromium (Cr)
  • Iron (Fe)
  • Magnesium (Mg)
  • Choline (Chol)
  • Inositol
  • Carnitine
  • Copper Zinc ratio

• Amino Acids: Amino acids, the building blocks of life, are essential for cardiovascular health. They combine in a myriad of ways to form proteins in our bodies. Nine of the 20 amino acids must be consumed through food.

One of the most notable amino acids for heart health is arginine or L-arginine. This amino acid transforms into nitric oxide (NO) in the body. NO is a potent vasodilator that helps blood vessels relax, improves circulation, and lowers blood pressure.

Other amino acids included in Level 1 testing are:

  • Asparagine
  • Glutamine
  • Serine
  • Arginine
  • Citrulline
  • Isoleucine
  • Valine
  • Leucine

• Antioxidants: Have you ever squeezed lime on an avocado to keep it from browning? The regular consumption of antioxidants like glutathione also prevents the inside of your body from rusting (so to speak)! Antioxidants are anti-agers that protect the body from free radicals and the oxidative stress they cause.

Glutathione is the most potent antioxidant in the body, protecting DNA and fighting inflammation. Without enough of it in our bodies to neutralize damage to the arteries, we are at increased risk of heart attack and stroke.

Similarly, coenzyme Q10 helps fight cardiovascular issues such as heart failure and high blood pressure. Unfortunately, our body’s stores of CoQ10 are depleted by various blood pressure and cholesterol-lowering medications. Therefore, it’s essential to test antioxidant levels in the body. Level 1 testing includes the following antioxidants:

  • Coenzyme Q10
  • Cysteine
  • Glutathione
  • Selenium

• Fatty acids: As an integral component of cell membranes, fatty acids play an essential role in cardiovascular health. Essential fatty acids are obtained by dietary fat, and an imbalance can cause various chronic health conditions.

A fatty acid panel examines a wide array of omega acids. For example, high levels of omega-3 fatty acids have been shown to reduce the risk of cardiac disease, lower blood pressure, and decrease cholesterol. On the other hand, too much omega-6 can result in blood clots, increased blood pressure, heart attack, and stroke.

Fatty acid panels evaluate the ratio of individual fatty acids to total fatty acids. In particular, fatty acid testing should examine the balance between omega-3 and omega-6 fatty acids in the body. Fatty acid imbalances often point to inflammation in the body. Included in Level 1 testing are:

  • Eicosapentaenoic acid (EPA)
  • Docosapentaenoic acid (DPA)
  • Docosahexaenoic acid (DHA)
  • Total omega-3
  • Arachidonic acid (AA)
  • Linolenic Acid (LA)
  • AA/EPA ratio
  • Omega-3 index

How are Level 1 tests completed?

Level 1 testing is completed through a routine serum blood draw. Level 1 testing can be done with an order at your local health center and generally takes less than a few minutes.

NHD Level 2 Testing

Play Video about Natural Heart Doctor Lab Testing Level 2

Level 2 testing is the most recommended testing package offered. Level 2 testing takes a deeper dive into cardiovascular and total body health status.

Who should consider this test?

Unfortunately, we live in a toxic world. Toxins are all around us, from the water we drink to the air we breathe. They live in our food, beauty products, and cleaning chemicals we use in our homes.

Since toxin exposure is unavoidable, nearly everyone could benefit from comprehensive testing to determine toxic load. Individuals with apparent exposures to mold, pesticides, and heavy metals should consider this test. Individuals with mystery health problems would benefit from Level 2 testing. Anyone interested in achieving their 100 Year Heart should obtain Level 2 lab results.

Natural Heart Doctor Level 2 Testing

What’s included in this test?

Level 2 testing sheds light on the various toxic exposures you may have unknowingly had. The result of your Level 2 testing will reveal your total toxic load. It will also indicate how these toxins and other life stressors have impacted your gut.

• Wheat Zoomer: “Gluten-free” is the latest buzz phrase in grocery stores and restaurants, and for good reason. Unfortunately, many people are sensitive to wheat or gluten and have no idea. It’s estimated that 1 in 7 people have a wheat-related disorder.

In these individuals, the body generates an immune response, releasing antibodies in response to the ingestion of wheat or gluten. The body responds to the “foreign invader” through inflammation. Systemic inflammation is responsible for a whole host of cardiovascular issues.

Individuals with a wheat or gluten sensitivity may experience:

  • Digestive problems
  • Low vitamin D levels
  • Chronic fatigue
  • Difficulty concentrating
  • Skin inflammation such as eczema or psoriasis
  • Chronic headaches
  • Weight gain or loss
  • Joint pain

Wheat Zoomer testing helps detect wheat and gluten-related disorders. By identifying antibodies to wheat peptides, including gluten and non-gluten components, the test helps determine the gut’s health.

The Wheat Zoomer will determine if an individual has leaky gut syndrome, celiac disease, a wheat allergy, or a gluten or wheat sensitivity. The final results provide a Wheat Zoomer score and an intestinal permeability score.

• Heavy Metals: Heavy metals accumulate in the air, soil, and water. While some professions or hobbies put individuals at higher risk for heavy metal toxicity, no one is fully protected from exposure.

Heavy metals are a common source of various health conditions, yet most people don’t even know they are a problem. As such, they are often overlooked. Heavy metals deplete critical vitamins, antioxidants, and minerals in the body.

Even low levels of heavy metal exposure can lead to cardiac issues such as:

  • High or low blood pressure
  • Swelling
  • Heart palpitations
  • Coronary heart disease
  • Peripheral artery disease
  • Anemia or other red blood cell abnormalities

Level 2 testing includes a screen for 20 of the most common heavy metals known to accumulate in the body. From mercury to lead, no stone is left unturned with this heavy metal testing.

• Mold Mycotoxin: Wherever there is water, the potential for mold exposure exists. Those at the highest risk for mold toxicity are individuals who live or work in older buildings, those who have known exposure to water-damaged facilities, and those with compromised immune systems. However, since water is everywhere, everyone should consider a mold mycotoxin test. Mold is breathed in and even makes its way into our bodies through the food we eat.

Mold toxicity is one of the most dangerous and least understood health conditions that individuals face today. Because the health effects of mold often mimic other illnesses, mold toxicity often goes undiagnosed. Mold symptoms may include:

  • Fatigue
  • Weight gain
  • Headaches
  • Muscle and joint pain
  • Brain fog
  • Digestive issues
  • Mood swings
  • Irregular heartbeat
  • Headaches
  • Frequent illnesses

Level 2 testing identifies 31 of the most common mold mycotoxins present in food and the environment. The mold mycotoxin panel gives a complete picture of an individual’s exposure to mold and the current levels in their body. Results are presented in three separate tables grouping the toxins into aflatoxins, trichothecenes, and other mycotoxins.

• Environmental toxins: Sadly, our world is a toxic place and is becoming more and more contaminated by the minute. From factory to transportation emissions, chemicals make their way into our air and water. They also seep into our bodies from cosmetics, household products, herbicides, and pesticides.

When these chemicals are absorbed, inhaled, or ingested into our bodies, they can wreak havoc on our health. Toxin overload manifests itself in various ways, impacting organs, tissues, and cells. They disrupt our endocrine, neurological, and cardiovascular systems.

Individuals with the any of the following symptoms should consider Level 2 testing:

  • Fatigue or weakness
  • Balance issues
  • Depression or anxiety
  • Hearing loss
  • Irregular heartbeat
  • High or low blood pressure
  • Joint pain or morning joint stiffness
  • Mood swings
  • Eye irritation or visual changes
  • Sleep problems
  • Skin rashes
  • Poor memory, difficulty finding words or concentrating

Level 2 testing examines 39 different environmental toxins, including pesticides, herbicides, phthalates, parabens, plastics, and VOCs.

Natural Heart Doctor Level 2 Testing

How are Level 2 tests completed?

Level 2 testing is completed through a routine serum blood draw and urinalysis. The first three tests require blood work, and the second three are evaluated through a simple urine sample that can be done at home and sent to the laboratory through the mail.

NHD Level 3 Testing

Play Video about Natural Heart Doctor Lab Testing Level 3

Who should consider this test?

Level 3 testing takes Level 1 and 2 testing up a notch. This test is ideal for individuals who have been searching for health answers but have been unable to find them. For example, perhaps you’ve not been feeling well, but your doctor gives you a clean bill of health. Alternatively, maybe you have a health condition that you are treating with medication but would like to heal the problem instead of masking the symptoms. If you want to achieve your 100 Year Heart, Level 3 testing might be the best place to start.

Level 3 testing with Natural Heart Doctor

What’s included in this test?

Level 3 testing includes all of the tests listed in Levels 1 and 2. However, it also offers three additional tests for a total of nine comprehensive views of your body.

• GI Effects: Our intestines are home to thousands of bacteria, both good and bad, that work together to perform many essential functions in the body. These bacteria, also called the microbiome, shape our immune system, help digest our food, and protect against bacteria that cause disease. Additionally, they help produce numerous vitamins needed for health and wellness.

When the bacteria in the gut becomes imbalanced, it leads to multiple health conditions and symptoms. Accumulating evidence suggests that alterations in the gut microbiome could play a significant role in heart disease. Other conditions and symptoms associated with poor gut health include:

  • Autoimmune disorders
  • Diabetes
  • Liver disease
  • Anxiety and depression
  • Inflammatory symptoms
  • Skin rashes
  • Small intestinal bacterial overgrowth (SIBO)
  • Frequent infections
  • Malnutrition
  • Food sensitivities

The GI Effects test is the most accurate microbiome test available to aid patients and healthcare providers in assessing and treating gastrointestinal disorders. This test can detect over 300 different species of microorganisms. You will know if you have bacteria, candida, yeast, parasites, and even worms through the GI Effects test.

The GI Effects test reveals three different types of microbiome imbalances:

  • An imbalance caused by good gut flora
  • An imbalance caused by an overgrowth of unhealthy bacteria
  • A lack of diversity in the type of flora found in the gut

• IBSSure: Irritable bowel syndrome (IBS) is the most common gastrointestinal disorder worldwide. It’s estimated that up to 15 percent of US adults live with this chronic condition, many of whom remain undiagnosed. What’s more, recent evidence shows that most individuals with an IBS diagnosis also have small intestinal bacterial overgrowth (SIBO).

IBS and SIBO are conditions that lead to various health problems beyond bloating, diarrhea, constipation, and stomach discomfort. For example, when our bodies cannot absorb adequate nutrients through the gut, including uptake of magnesium and B vitamins, it can impact heart rhythm. Additionally, an overgrowth of “bad bacteria” in the gut leads to systemic inflammation, which can trigger heart disease.

The IBSSure is a simple blood test that detects two antibodies often present in individuals with irritable bowel syndrome. This test identifies two markers that show if the gut is not working/moving correctly:

  • Anti Cytolethal Distending Toxin B (Anti-CdtB IgG and IgA)
  • Anti-vinculin IgG and IgA

Since all health starts in the gut, individuals who complete Level 3 testing and receive a diagnosis of IBS or SIBO can take measures to heal the gut, thus healing other conditions in the body.

• Tick-Borne testing: The prevalence of tick-borne illnesses has risen significantly in the past decade. Ticks transport tick-borne diseases, including Lyme disease, anaplasmosis, babesiosis, and Rocky Mountain spotted fever.

Because ticks are small and difficult to detect, symptoms often mimic other conditions, and these diseases often go undiagnosed. Unfortunately, tick disease can lead to many health problems if left untreated, including cardiovascular disease. Lyme bacteria can enter the heart, disrupting the electrical system and causing inflammation.

Individuals with tick-borne infections may experience:

  • Unexplained fevers
  • Headaches
  • Neck stiffness
  • Fatigue
  • Muscle aches or joint pain
  • Skin rashes
  • Weight loss
  • Dizziness
  • Shortness of breath
  • Gastrointestinal symptoms such as nausea or diarrhea
  • Heart palpitations

Level 3 testing includes a comprehensive tick-borne panel. The tick-borne testing examines numerous antibodies and PCR tests to determine if you have been infected with Lyme disease or other co-infections.

Level 3 testing takes a deeper dive into the health of the immune system and the gut.

How are Level 3 tests completed?

Level 3 testing is completed through a routine serum blood draw, urinalysis, and stool sample. The urinalysis and stool sample can be collected at home and sent via mail to the laboratory.

NHD Level 4 Testing

Play Video about Natural Heart Doctor Lab Testing Level 4

Who should consider this test?

Level 4 testing is the most advanced, in-depth health analysis available through the Natural Heart Doctor. This comprehensive test is the Cadillac of health testing.

Level 4 testing looks at all aspects of health, including the cardiovascular, gastrointestinal, immunologic, and neurologic systems. This test package is ideal for individuals seeking the most up-to-date, in-depth analysis of total body health and wellness. It is the ultimate strategy to keep you on the path to your 100 Year Heart.

What’s included in this test?

Level 4 testing is a sum of Levels 1, 2, and 3, plus three additional tests. Individuals who choose Level 4 testing will receive a total of 12 comprehensive tests.

• Neural Zoomer Plus: Many individuals who experience brain fog, memory loss, weakness, or neuropathic pain tend to dismiss it, chaulking the symptoms up to aging. Fortunately, this could not be further from the truth. Healthy aging should not include a noticeable decline in cognitive function.

Instead, inflammation is involved in nearly all cases of brain dysfunction. The Neural Zoomer Plus Test is an exam that looks at 48 neurological antibodies to determine the level of autoimmune disease in the brain.

By identifying the body’s response to these neurological antigens, practitioners can help lower inflammation and treat the brain symptoms by addressing the root cause. Individuals with any of the following symptoms or diseases would benefit from Neural Zoomer Plus testing:

  • Memory loss
  • Balance problems
  • Weakness
  • Dizziness
  • Cognitive impairment
  • Seizures
  • History of concussion
  • Visual decline
  • Alzheimer’s disease
  • Parkinson’s disease
  • Multiple sclerosis
  • Myasthenia gravis
  • Dementia
  • Autism

The underlying cause of neurological diseases is often inflammation caused by stress, environmental triggers, toxins, diet, and infections. The Neural Zoomer Plus helps determine the level of chronic inflammation impacting the brain. If the brain is inflamed, so is the heart.

• Neurotransmitter Panel : Neurotransmitters are the chemical messengers that help transmit signals in the brain and through the central nervous system (CNS). Neurotransmitters are involved in various processes, including emotions, pain response, energy, and mental performance.

All of the hormones of the body are interconnected with neurotransmitters. Unfortunately, most health practitioners don’t evaluate neurotransmitter imbalances. Since the two play off one another, having a solid picture of both helps determine the root cause of symptoms.

Conditions and symptoms associated with neurotransmitter imbalances include:

  • Mood disorders such as depression and anxiety
  • Loss of mental focus or memory
  • Fatigue
  • Sleeping difficulties
  • Excessive anger
  • Addiction/dependency issues
  • Weight gain or loss
  • Frequent food cravings
  • Sexual dysfunction

Neurotransmitter testing examines the various neurotransmitters in the brain, such as serotonin, dopamine, histamine, and GABA.

• CardiaX: Many people believe that they are destined for an unhealthy life due to their family history. However, while genetics undoubtedly play a role in health, research finds that lifestyle choices have an enormous impact on health outcomes, especially those related to the heart.

CardiaX testing is a genetic screening tool that provides individuals with their predisposed risks to heart disease based on genetic markers. CardiaX testing may be beneficial for individuals with:

  • Family history of heart disease
  • Elevated inflammatory markers
  • Uncontrolled high blood pressure
  • History of cardiac events
  • Diagnosis of metabolic syndrome
  • Diagnosis of Atrial fibrillation, blood clots, or stroke

By understanding their genetic risk factors, individuals can make wise lifestyle choices aimed at prevention.

Level 4 testing blood work

How are Level 4 tests completed?

Level 4 testing is completed through a routine serum blood draw, urinalysis, and stool sample. The urinalysis and stool sample can be collected at home and sent via mail to the laboratory. Additionally, individuals can choose to take the CardiaX as a cheek swab at home.

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.

Will my insurance cover the cost of a Natural Heart Doctor Online Second Opinion?

Most likely, no. Most health plans do not cover online second opinions or consultations. You are responsible for the cost of our second opinion. Natural Heart Doctor cannot file a claim with your insurance carrier, nor can we provide a procedure (CPT) code for this service.

What is the timeline to receive an online second opinion?

We do our best to schedule your second opinion as quickly as possible. Typically, it takes 5 to 7 business days after your information has been collected to receive your phone or video online second opinion.

What information do you need in advance of our call?

Our office will send you a short questionnaire to complete and return. We DO NOT need your complete medical records.

How many questions can I ask the expert during our call?

You may ask a maximum of five questions. This is to ensure that the expert has sufficient time to devote to each question. All questions must be finalized before your online meeting.

What should I expect to receive once my second opinion is complete?

You will receive a summary of our discussion along with our second opinion. The second opinion will be in written form. After you have reviewed the second opinion, a Natural Heart Doctor clinician will follow up with you by phone to address general medical questions about the information provided in the second opinion.

What if I have follow-up questions for the expert after I have reviewed my second opinion?

If you have a clarifying question about an expert’s response to one of the questions in your second opinion, and the Natural Heart Doctor clinician is unable to address it, then you may request a follow up session for an additional fee. 

Is my medical and payment information secure?

Natural Heart Doctor is strongly committed to protecting the privacy and security of all our patients. Our website meets all federal requirements for protecting personal health information under the Health Insurance Portability and Accountability Act (HIPAA). All financial transactions are processed by Natural Heart Doctor securely using industry standard payment processing tools.

I would rather visit Natural Heart Doctor for an in-person appointment. What should I do next?

If you would prefer an in-person appointment at Natural Heart Doctor instead of an online second opinion, please call (480) 535-6844 for details and scheduling.

Can I schedule a follow up appointment with the specialist who provided my online second opinion?

Yes, we’re happy to help you on an extended basis. Our clinician can discuss options with you when presenting our second opinion summary.
