The Bio-Tracker can test your DNA, for patients who cannot get into the office or cannot sit for an hour for the test. You can mail or drop off your sample for testing. With a cotton swab or Q-tip, swab the inside of your cheek to thoroughly moisten the swab and place into a clean plastic baggie. Cut a small sample of hair at the scalp and place in a separate, clean plastic baggie. Fill out the "Patient Symptom Survey" (PSS) found under Nutrition forms. Send or drop off the PSS with both samples for testing. When complete, your results and remedy (if applicable) will be sent to you.
