Laboratory Certification (CLIA)

The Laboratory Certification Program works to ensure Ohioans receive accurate, cost-effective clinical laboratory testing as a part of their health care. Clinical laboratory testing directly or indirectly affects every Ohio resident from pre-cradle to grave.

Each year, the program inspects and monitors clinical laboratories located in hospitals, independent laboratories, plasmapheresis centers and physicians offices. The program monitors the performance of approximately 8,500 laboratories and investigates clinical laboratory complaints it receives.

The program monitors all clinical laboratories for compliance to federal (42 Code of Federal Regulations Part 493 Clinical Laboratory Improvement Amendments of 1988 (CLIA)) and state requirements (Ohio Revised Code Chapter 3725 Plasmapheresis Centers). The program conducts on-site inspections for compliance, monitors accuracy and reliability of testing via proficiency review of testing scores/reports, investigates complaints and answers both regulatory and technical questions related to clinical laboratories.

New Applications:
Generally, each separate location or address is required to have a separate CLIA number. There are exceptions for not-for-profit/government-owned laboratories or hospitals. Call us if you think your organization qualifies for one of these exceptions. See the application links on the side bar.
