If your physician was trained by Dr William Walsh, PhD., to manage mood and behavior disorders, these are the key tests that will be ordered to determine your Biotype.

The Comprehensive Biotype Panel is typically the first panel ordered when determining Biotypes. The other panels may be selected if some of the tests have already been completed, or when retesting to assess progress with nutrient supplementation.

If you do not already have a practitioner who can assist with reading these results, you may choose to consult with Second Opinion Physician. We can also assist with finding other practitioners to order these tests in states such as NY, NJ and MD.
