Functional Laboratory Testing

Functional laboratory testing can be a valuable tool and provide insights into complex chronic health conditions as well as those who are seeking optimal wellness. Some testing can be performed in the comfort of your own home. In addition, some functional laboratory testing can be performed and billed under insurance. For more details please contact our office. Ome examples of these tests are listed below:

Functional Thyroid Testing:

Often standard thyroid labs are not enough to determine thyroid dysfunction. A full functional thyroid workup can determine autoimmunity and true levels of thyroid hormone. Quest Analytics and LabCorp are two key laboratories that offer this service and is often covered by insurance.

Heavy Metals Testing

A cost-effective and easy way to assess for heavy metals is a hair metals test. We work with several laboratories that offer this service. Please contact our office for more info.

Organic Acids Test (OAT Test)

An organic acids test often referred to as an OAT Test, is a foundational functional medicine test that is a "metabolic snapshot of a patient's overall health". It's commonly ordered for many patients and is recommended as a baseline test after the initial appointment, especially if the patient is dealing with mood disorders, fatigue, digestive complaints, or weight issues.

The OAT test looks at organic acids in urine produced in a patient's metabolism. It's offered by many different labs, with the most popular being Great Plains Laboratory and Genova Diagnostics. The test provides an accurate evaluation of intestinal yeast and bacteria. The OAT test by Great Plains also includes markers for vitamin and mineral levels, oxidative stress, fungal levels, Clostridium, neurotransmitter levels, and oxalates, which are highly correlated with many chronic illnesses.
