A laboratory is defined as any facility which performs laboratory testing on specimens derived from humans for the purpose of providing information for the diagnosis, prevention, treatment of disease, the impairment of, or assessment of health.

Under the CLIA regulations, the federal Centers of Medicare and Medicaid Services will inspect any size laboratory for adherence to the CLIA requirement. Next Genomix Laboratory is fully certified under the federal law of the United States of America called CLIA. CLIA # 11D2154238.

Congress passed the Clinical Laboratory Improvement Amendments (CLIA) in 1988, establishing quality standards for all laboratory testing to ensure the accuracy, reliability and timeliness of patient test results regardless of where the test was performed. However, if a state agency has an acceptable laboratory inspection program, then that state can perform the necessary laboratory inspections. If that laboratory complies with all of the quality control procedures, that laboratory is then awarded a CLIA license. The CLIA license means the laboratory has met all federal requirements for operating a laboratory. Reach out with questions today.
