Laboratory Testing

The laboratory testing done in Functional Medicine is one critical part of creating your personalized treatment plan.  Blood tests are done at our Center, or at an outside lab.  Stool, urine and saliva are done in your home with a special kit. Some of the Functional Medicine laboratory testing we routinely do include the following:

The Bowel Function Test:

Stool analysis that evaluates your ability to digest and absorb food, the presence and quantity of beneficial bacteria, harmful bacteria, and yeast. SIBO breath testing for small intestinal bacterial overgrowth. Problems in these areas can be the underlying cause for many clinical symptoms and conditions such as immune dysfunction, irritable bowel, fibromyalgia, migraines, and more.

Nutritional Testing

This special blood test measures vitamin and mineral levels inside your cells, which is more accurate than routine serum levels. This is an important basic screening for both the prevention and treatment of all medical conditions.

Urine Organic Acid testing looks for blockages in your biochemical pathways, which tells us if you are functionally deficient in any vitamins. This is the best way to measure vitamins by assessing the function of enzymes.  For more information, visit www.gdx.net.

An Amino Acid Profile is a blood test to assess the levels of these protein building blocks that are needed to build healthy tissues throughout the body, such as hair, muscle, neurotransmitters and immune cells. This is important for people with hair loss, depression or fatigue, and especially useful for vegans and vegetarians to determine if you are getting enough protein. For more information, visit www.gdx.net.

Nutrient and Toxic Element Profile is a blood test that determines the levels of essential minerals in the body as well as toxic elements such as aluminum, arsenic, lead, cadmium and mercury. For more information, visit www.gdx.net.

The most complete, bundled profile is the NutrEval, which combines the above-mentioned Urine Organic Acid testing, Amino Acid Profile, fatty acids, antioxidant vitamins, lipid peroxides, and nutrient and toxic elements. Tests are bundled together for a discounted price.  For more information, visit www.gdx.net.

The TRIAD is a great option; a combination of three of the above tests – Organic Acids, Amino Acids, and IgG food allergy testing – for the price of two. For more information, visit www.gdx.net.

Hormone Evaluation

Adrenal Testing: This is a saliva test to evaluate adrenal fatigue by measuring cortisol and DHEA levels throughout the course of the day.  This is especially helpful for those with excessive fatigue, inflammatory conditions, hormone imbalance, and weight issues. For more information, visit www.gdx.net.

Estrogen Metabolism Testing: This is a urine test that measures estrogen metabolites that indicate how well your body is detoxifying and eliminating estrogen. This is important for women with a history of breast cancer, at risk for breast cancer, or interested in prevention. For more information, visit www.gdx.net.

Female Hormone Level Testing: This is a saliva test to quantify estrogen and progesterone levels and to determine need for supplementation and assist in adjustment of estrogen supplementation doses. For more  information, visit www.aeron.com.

All other hormone testing, including basic male and female hormone levels, as well as thyroid evaluation is done through the lab of your choice – typically based on your insurance.

Food Allergy Evaluation

Food Allergy IgG testing is a blood test that measures IgG levels to 90 different foods. This goes beyond the tests typically done by allergy  specialists. It can help you identify food triggers for many health conditions, increased intestinal permeability, or leaky gut, gluten sensitivity, and celiac disease. For more information, visit www.gdx.net. We also offer more comprehensive food allergy and cross-reactivity blood testing through Cyrex labs. For more information, visit www.cyrexlabs.com.

Heavy Metal Testing

We use a special overnight urine collection to assess your total body burden of mercury, lead, arsenic and cadmium. This goes beyond a blood test that can only measure current exposure.  This is especially useful for those with autoimmune conditions, severe fatigue, neurological symptoms, unexplained symptoms, or environmental exposure. For more information, visit www.doctorsdata.com.

We also offer a blood test to evaluate your current exposure to heavy metals called a Nutrient and Toxic Elements test. For more information, visit www.gdx.com.

Anti-oxidant Status

Urine test to measure markers of free radical damage, which reflect your body’s level of anti-oxidants. This is important for anyone with neurological illness or symptoms, and as a basic screening to know if you need more anti-oxidants. For more information, visit www.gdx.com.

Genetic Testing

Detoxigenomic: Saliva test to assess the potential genetic handicaps in your detoxification pathways. Impaired detoxification is an underlying issue for many health conditions, including autoimmune disease, migraines, fibromyalgia, allergies and chemical sensitivities. This is especially important for those taking multiple medications as these use up detoxification enzymes and can cause deficiencies in the pathways.    For more information, visit www.gdx.com.

Estrogenomic: This is a saliva genetic test that evaluates genes that determine susceptibility to breast cancer, osteoporosis, and cardiovascular disease. For more information, visit www.gdx.com.

Cardiovascular Testing

Blood test that evaluates overall cardiovascular risk with comprehensive cholesterol (particle analysis), inflammation, and metabolic markers.  For more information, visit www.hdlabinc.com.

Neurotransmitter Testing

Urine test that measures neurotransmitter metabolites. This is important for those with sleep problems, depression and other mood disorders. Results can direct treatment with amino acid supplementation to balance neurotransmitters instead of using anti-depressants or anti-anxiety medication. This is also useful to help guide a weaning-off medication program.  For more information, visit www.neuroscience.com.

Lyme Disease Testing

We offer specialized blood testing by the premier lab in the country for Lyme and other tick-borne diseases. For more information, visit www.igenex.com.
