The American Board of Medical Laboratory Immunology (ABMLI) certified doctoral-level immunologists seeking to direct laboratories engaged in the practice of medical laboratory immunology. ABMLI certification is recognized by federal and state governmental agencies as a significant component toward meeting licensure requirements to direct laboratories engaged in the microbiological diagnosis of human disease. It is recognized under the Clinical Laboratory Improvement Amendments of 1988 final rule and in the 11 states that require licensure: Florida, Georgia, Hawaii, Louisiana, Montana, Nevada, New York, North Dakota, Rhode Island, Tennessee, and West Virginia. 

The ABMLI phased out its certification exam and is no longer accepting new Diplomates. The ABMLI will continue to serve its Diplomates through recertification, maintaining an active roll of Diplomates and verification of certification status.  The Centers for Medicare and Medicaid Services has confirmed that it will continue to recognize ABMLI certification as a personnel requirement for high-complexity laboratory directors even though the exam will no longer be offered. Learn more about the phase out.
