Riordan Clinic

Introduction to Our Services Bio-Center Laboratory (BCL) was established in 1975 and has dedicated itself to providing accurate clinical assays 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. Repeat Testing: In most cases, unusual test results are automatically repeated by the laboratory and noted as such on the final report. If you question a result, please call client services and we will further evaluate the result and repeat the test if necessary, at no charge, provided that we have sufficient quantity of specimen to do so. For the most part, specimens are retained for at least one month.
