Your Guide to Functional Medicine Lab Testing

Cutting-edge diagnostic testing is essential to identify the source of your medical issues and
charting your path to optimal health and wellness.

This guide will give you an overview of the main tests functional medicine doctors like Dr. Sarah Williams here in Concord, MA, and the surrounding areas use to get to the root of your health problems.

When it comes to food sensitivity testing, not all tests are created equal. The Cyrex 10-90 Food Antigen Panel tests for sensitivity to not only at raw, cooked & combinations of foods, but also to food additives & cross-reactions between foods.

Digestive problems

Gut health is key to your overall health. The Cyrex Array 2 tests for the presence of intestinal permeability or "leaky gut". A leaky gut is often seen in individuals with digestive disorders, food sensitivities as well as autoimmune conditions.

Gluten Free

Gluten sensitivity doesn't just affect your gut. It can also have a negative impact on your immune system, your. neurological system as well as your mood. The Cyrex 3 Array evaluates markers for these categories as well as for Celiac Disease.


Pathogens such as viruses, bacteria, parasites, mold, and yeast can

play a role in the development

of autoimmune reactivity.

The Cyrex 12 Pathogen-Associated Immune Reactivity panel screens for the presence of antigens which may lead to autoimmune reactions in multiple organs throughout your body.


The initial signs of an autoimmune condition are often overlooked. This is why functional medicine testing is so important. A functional medicine doctor can help find overlooked autoimmune disorders, like Lyme disease, so proper treatment can begin. Some of these methods could be hormone testing, checking thyroid health, and taking physical factors like recent weight gain, or skin changes.

The Cyrex 5 Autoimmune Panel blood tests for the presence of antibodies that can herald an autoimmune illness prior to the development of symptoms.

Cardiac IQ

Not all cholesterol panels evaluate key factors that determine your risk of cardiometabolic disease.

Cardiac IQ offers advanced lipid profile testing.

Exclusive immunophenotyping to help identify immune deficiency, immune over-activity, infections, inflammation, autoimmunities, allergies, asthma, hypersensitivities, and cancers.
