Path to Health

Functional Testing

The functional medicine model is an individualized, patient-centered, science-based approach that empowers patients and practitioners to work together to address the underlying causes of disease and promote optimal wellness.

Functional medicine is:

  • The science of treating health.
  • Treating the whole system, not just the symptom.
  • Focusing on the whole organism, not just the organs.
  • The medicine of why.
  • The future of medicine. It shifts the approach from a disease-centered approach to a patient-centered approach.

Many health-related conditions stem from imbalances and nutritional deficiencies that need to be corrected in order for healing to occur. Therefore, professional-grade supplements and dietary changes may be suggested for you. During a consultation, we will determine which tests are needed. These tests assess nutritional status, mitochondrial function, digestive function, food allergies, hormone imbalances, toxin exposure, and more.

A disease state or condition can be caused by many different factors, including inflammation, poor gut health, nutrient deficiencies, lifestyle choices, diet, etc. The precise manifestation of each cause depends on an individual’s genes, environment, and lifestyle. Only treatment that addresses the right cause will successfully treat the condition and have lasting benefits for the individual. Functional medicine is not a drug free approach, but an integration of health, wellness, and root-cause medicine that works alongside conventional/allopathic medicine.

Jaime Reid  can help patients manage the bridge between conventional medicine and the use of pharmaceuticals and the desire to utilize supplements and a more natural approach to treat disease. Schedule your functional medicine consultation today!

At Williamsburg Drug Company, we are happy to announce our functional testing options:

Spectracell’s Micronutrient Test (MNT) will tell you exactly the micronutrients in which a patient is deficient. It evaluates how 31 different vitamins, minerals, amino acids, and antioxidants are working within a person’s cells. But it goes even further—The MNT will tell how well cells can withstand oxidative stress, how well cells are metabolizing carbohydrates and how adeptly cells function when launching an immune response.

LPP® addresses 2 main issues when looking at the low-density lipoprotein (LDL) particles that carry the cholesterol throughout the blood, not the cholesterol within them: 1 – assessing risk of current lipoprotein particles and 2 – how best to treat these risks. Measuring the lipoprotein subgroups is the only way to evaluate new risk factors, which is crucial for an accurate assessment of cardiovascular risk—according to the National Cholesterol Education Program (NCEP).

The adrenal glands, otherwise known as the “stress glands,” enable our bodies to cope with stress and survive. Whether stress comes from outside in the form of a natural disaster, or from within like the anxiety we experience before public speaking, it’s the adrenals’ job to help us adapt to the situation. Patients can conduct a saliva cortisol test or a urine cortisol test to assess adrenal hormones by collecting four non-invasive samples over the course of one day.  ZRT is able to generate results with a diurnal cortisol curve, which reveals cortisol levels throughout the day and allows health care providers to pinpoint issues with adrenal gland function.

The ZRT Sleep Balance Profile can reveal the cause of sleep disruption so that correct measures can be taken to restore a healthy sleep pattern through a urinary measurement of the melatonin metabolite 6-sulfatoxymelatonin (MT6s) in relation to cortisol and cortisone levels. Quite often, difficulty falling asleep can be related to stress and elevated nighttime cortisol levels. Low night time melatonin is often the result of too much light and activity late into the evening. Lifestyle measures and proper sleep hygiene can change the ratio between cortisol and melatonin allowing for a more restorative night’s sleep.

Neurotransmitters are chemical messengers used by the nervous system to relay information from one nerve to another. Optimal neurotransmitter balance is required to maintain proper health. ZRT has determined that, only by looking at the parent neurotransmitters with downstream metabolites, that you can tell whether there is a systemic pattern. ZRT Laboratory includes a range of 14 neurotransmitters and metabolites in its testing. This essential collection of tests is available only from ZRT – and not from any other lab.

Heavy metal exposure is on the rise. Common sources include cigarettes, seafood, rice, well water & dental fillings. Getting too much, and sometimes too little, of various elements has consequences for our overall health. ZRT’s heavy metals and essential elements testing provides the most accurate test results. Using ICP-MS, the gold standard for element analysis, allows for high specificity and sensitivity into the parts-per-trillion. Essential elements are abundant, too, and only healthy when they are within optimal ranges. Nutrients like copper, iodine, magnesium, selenium and zinc are critical for enzymes that synthesize neurotransmitters and activate hormones. Bromine and lithium, while not currently classified as “essential” elements, have been shown to play a positive role in health but are also potentially toxic at excessive levels.

Inflammation linked to food allergies or sensitivities is often connected to anxiety, depression, bloating, stomach pain, inability to lose weight, impotence, libido, fatigue, insomnia, joint pain, constipation or diarrhea, and sugar cravings. The FIT Test will identify the foods you are most sensitive to. This is a very extensive test which detects both IgG antibodies and Immune Complexes to determine their reactivity against a wide range of food antigens. It measures sensitivities to 132 foods in all major food groups such as dairy, grains, fruits, meats, nuts, fish, seeds, beans, fowl, shellfish, vegetables, spices, microbes, additives, and extracts.

The gut microbiome plays a critical role in mediating the effects of diet and other factors on health, including digestive, immune, metabolic and neuroendocrine functions. Assessing GI health with the proper tools can help practitioners get to the root cause of chronic illness. The GI-MAP (Microbial Assay Plus) is unique in the field of comprehensive stool testing. It relies exclusively on quantitative polymerase chain reaction (qPCR) technology to detect parasites, bacteria, fungi, and more, by targeting the specific DNA of the organisms tested. The GI-MAP’s accuracy and reliability allows practitioners to create personalized treatment protocols to address gut dysfunction based on which infections are urgent, which areas of the gut are already optimized, and which areas should be addressed after an infection is resolved.

Heart disease refers to a variety of conditions that affect the heart—from infections to genetic defects and blood vessel diseases. Most heart disease can be prevented with a healthy lifestyle, yet it’s the number-one health threat in the world, so it’s important that your know your cardiovascular numbers. Vibrant America offers the most relevant tests available to assess your risk or for monitoring current conditions.

Serum thyroid stimulating hormone (TSH) level is the most sensitive and specific laboratory indicator of primary hyperthyroidism or primary hypothyroidism. In most patients, TSH level provides a physiologic indicator of the functional level of thyroid hormone activity and thyroid metabolism and is the primary test used to assess thyroid function.

Hormones play an important role in women’s health. Estrogen and progesterone are probably the most important hormones when evaluating reproductive health. In addition to these sex hormones, your body also makes and uses other important hormones that can have an effect on your overall health, such as your energy level, weight, mood, and sleep patterns.
