Since 1986, Dr. Krystosik has helped customize his patient’s health care  plans using state of the art functional medicine tests. From a blood  test to identify the exact foods right for each individual, a comprehensive stool test to provide a five-page  report on the levels of good and bad and bacteria living in the gut, and the ability to digest  carbs, fats and proteins, plus levels of inflammatory markers in the gut  and more, or any other functional medicine test, Dr. Krystosik will  work hard to uncover the underlying cause of your illness.
