The Bio-Center Lab at the Riordan Clinic was established in 1975 and has dedicated itself to providing accurate clinical analysis focusing on nutritional medicine. Our specialties include testing for pyrroles, histamine, spermidine, spermine, cytotoxic food sensitivities, parasitology, analysis of red blood cell fatty acids and minerals, along with many vitamins.
The Lab’s function at our facility 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.
Why choose the Bio-Center Laboratory
- Quality Control – Samples are processed at the Bio-Center Lab which offers a high degree of quality control. You know your samples are not being shipped to some other state or country for analyzation. This also allows us to be more “green” by eliminating fossil fuel usage in transporting samples.
- Faster Turnaround – Because of the on-site lab, samples are processed and results returned expediently.
- Certified – We are a CLIA certified reference laboratory. External certifications provide for exceptional reporting accuracy.
- Unique Tests – Bio-Center Lab performs unique tests on blood and urine that other laboratories do not perform: blood histamine, spermidine, spermine, urine pyrroles, and plasma vitamin C by HPLC. This offers our doctors a unique insight into helping identify patient needs.
