About Bio-Center Lab

Dedicated to discovering nutrition-based solutions for better health.

The Bio-Center Laboratory was established in 1975 and is housed on the Riordan Clinic campus. Our lab is dedicated to providing accurate clinical analysis focusing on nutritional levels. Our specialties include testing for* pyrroles, histamine, parasitology, analysis of red blood cell fatty acids and minerals, along with many vitamins.

We have done exhaustive research to determine which test methodologies and specimen types will yield the most clinically significant results. We have been performing and innovating many of our specialty tests for more than 45 years. Our pyrroles tests are still one of the most requested reference tests we perform. In fact, we are proud to be the laboratory that many other labs choose to do their pyrroles testing.

The function of our laboratory is two-fold: to provide in-house patients who come for treatment with an 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.

All tests listed and sold on this website are from the Bio-Center Laboratory. Doctors who wish to order kits, please call our lab directly to set up an account. 316-684-7784

Who needs lab testing?

Every person is biochemically unique. We all have different nutritional needs based on our hereditary factors, environmental factors, diet, lifestyle choices and even phase of life. (As an example, a menopausal woman has different needs than a pregnant woman.) To find out what your individual needs are, getting your nutrient levels tested is critical.

Why choose the Bio-Center Laboratory?

Quality Control

Samples are processed at our on-site lab which offers a high degree of quality control. Many physicians feel that our choice of sample and methodology has provided them with more accurate results from more stable samples.

Faster Turnaround

Because it is located right on the Riordan Clinic campus, samples are processed and results returned expediently.


We are a CLIA-certified reference laboratory. External certifications provide for exceptional reporting accuracy. On our last inspection, we received zero deficiencies, only 5% of the inspected laboratories can make that claim. In order to ensure we meet the highest standards and provide quality, reliable test results, we have had continuous certification from state and federal agencies since 1976.

Unique Tests

Our lab performs innovative nutritional and biometric testing on blood, hair, and urine that other laboratories do not offer or specialize in. We are known for being national leaders in the measurement of urine pyrroles and plasma vitamin C. This wide array of specialty testing offers doctors clear and quantifiable insight into helping identify the root causes of disease based specifically on an individual’s unique biochemical makeup.


We get orders from all over the world and we ship kits out on a regular basis. Our lab personnel have more than 100 years of combined laboratory experience, including lab techs with 10+ years of experience in the field, some with more than 40 years. We also have an MD on staff to consult with patients or other physicians.
