Functional Medicine and Functional Testing

The use of the word "functional" is key to understanding the integrative medical approach.  Chas Gant, MD, PhD,  uses many tests to determine how the body or organ is currently functioning, or working, as compared with normal, healthy functioning. Functional tests help determine how the body or organ is really working, as opposed to other medical tests which measure pathological breakdown and disease.

A sub-optimal functional test may indicate a need for correction even though traditional testing may show everything is within the normal range. This is a subtle but important difference as many sub-optimal health conditions will cause symptoms that get us to the doctor, but then no reason can be found for what is causing our health problem.


What is Functional Medicine?

Functional Testing Looks for the Root Cause of Imbalance

Functional medicine searches for the underlying imbalance, or root cause, which can contribute to illness or chronic disease. If you have an imbalance, it can affect your body in many ways. Functional changes occur long before disease is manifested, so functional testing becomes an early warning test for disease which is ideal for prevention-oriented physicians and patients concerned about finding the root cause of their problem.

We offer amino acid precursor therapies to help restore the imbalanced neurotransmitters that may have caused ADHD, or Addiction to alcohol or substances in the first place. Functional laboratory testing may determine what your specific nutritional and metabolic imbalances and toxicities are, so that your unique "body" or physical causes of addiction can be pinpointed and corrected. These amino acid and nutritional therapies can be delivered through nutritional supplements, intravenously and transdermally (through the skin).

Degenerative neurologic diseases such as Parkinson's, Alzheimer's, Multiple Sclerosis, and early Dementia are often an expression of neurotoxicity. This can come from mercury, pesticides, mold, or other toxins. Clearing out the toxic load through a sound program of detoxification is always worthy of consideration.

Special Lab Testing - Diagnostic Functional Testing

Our model of Functional Medicine involves special lab diagnostic testing, called Functional Testing. These lab tests are often covered by insurance and help to identify and correct imbalances in the brain and body chemistry. Imbalances such as these may be early symptoms of disease or barriers to good health.

Functional Medicine lab tests may uncover:

  • Nutritional Deficiencies
  • Hormonal Imbalances
  • Detoxification and Biotransformational imbalances
  • Immune imbalances
  • Inflammatory imbalances
  • Digestive,absorptive, and microbiological imbalances
  • Structural imbalances
  • Methylation issues
  • Genetic issues, MTHFR and COMT genes


Expert Interpretation of Results

Chas Gant has over 30 years experience in interpreting these complex tests. Based on his findings, he creates a plan for each patient to correct their imbalances and restore fundamental health.
