Functional Testing

We provide several unique types of blood, hormonal, and allergy testing to investigate the root cause of issues in the body that may be affecting your health.

Each of the tests below is available for anyone doing a nutrition program at PSI. They are currently not offered as standalone services.

Bio-Impedance Analysis

To monitor progress for all of our nutrition programs, we use Bio-Impedance Analysis (BIA) testing, which measures lean body mass, body fat, cell hydration, and a marker of overall cell health. These measurements allow us to create a comprehensive nutrition program specific to each individual and make ongoing refinements to ensure progress.

We also do a BIA with all new members as a complimentary service!

Immunolabs Food Sensitivity Panel

“One man’s food may be another man’s poison.” About 70% of all chronic disease is preventable, and is in large part, tied to inflammation. Food intolerances arising from both genetic and environmental factors, can often cause or exacerbate problems such as aching joints, sport injuries, difficulty losing weight, poor concentration, poor energy, headaches, congestion, skin disorders, GI issues, and many others.

The Immunolabs Bloodprint test identifies these inflammatory foods, and helps us fine-tune our programs even further for your specific needs. (

SpectraCell Comprehensive Nutritional Panel

This test measures intracellular levels of 34 vitamins, minerals, amino acids, fatty acids, metabolites, and antioxidants, as well as immune function, all of which are required for both optimal performance and health. Most of us, even those taking supplements already, have sub-optimal of these key nutrients, which can have a myriad of negative effects on performance and recovery, immune health, energy, and even anti-aging.

We review the results with you and put together a specific supplement and diet plan to help get levels back in range. (

SpectraCell Telomere DNA Aging Analysis

This test measures the telomeres on the end of your DNA strands to determine how the aging process is affecting the lifecycle of your cells. In a nutshell, it tells you if your lifestyle, diet, and exercise are positively or negatively affecting your aging process. (

SpectraCell MTHFR Genotyping

MTHFR is an enzyme responsible for converting 5,10-methylenetetrahydrofolate to the product 5-methyltetrahydrofolate and is involved in the metabolism of folate and homocysteine. The test provides critical information relating to the most common MTHFR mutations.

Who should get tested? Those with a family history of cardiovascular risk, autism, chemical sensitivity, cancer risk, and/or miscarriages. Better understanding your MTHFR gene can help navigate additional nutritional requirements needed for optimal health if you have one of the MTHFR genetic mutations. (

Labrix Comprehensive Hormone, Neurotransmitter Test

This test will evaluate your neuro-endocrine (neurotransmitters and hormone levels) and immune systems. Imbalances in these systems occur as a result of exposure to psychological or physical challenges. Underlying stressors, such as mental or emotional stress, poor diet, unhealthy lifestyles, infections, environmental toxins, and general immune system up-regulation will alter the neuro-endocrine and/or immune system(s). Addressing symptoms while identifying and treating the root cause will get your system back in balance. (
