The on-site laboratory at the Riordan Clinic was established in 1975, originally as the Bio-Center Lab. Our lab is dedicated to providing accurate clinical analysis focusing on nutritional medicine. Our specialties include testing for pyrroles, histamine, cytotoxic food sensitivities, parasitology, analysis of red blood cell fatty acids and minerals, along with many vitamins.

The function of our laboratory is two-fold: to provide in-house patients who come for treatment with accurate state of the art laboratory analysis and to provide diagnostic services for physicians and hospitals throughout the country. In both cases, we provide doctors relevant biochemical impairment information to increase diagnostic accuracy.

The lab is an open lab, so most tests can be self-ordered without a doctor’s referral.
