American Board of Medical Microbiology Certification

August 2022: Please be advised that the application deadlines and some eligibility requirements have changed.

The American Board of Medical Microbiology (ABMM) exam certifies doctoral-level microbiologists to direct medical and public health microbiology laboratories. ABMM 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. The ABMM certification is a U.S. Department of Health and Human Services (HHS) approved board certifying a laboratory director of high complexity testing. The ABMM is recognized under the Clinical Laboratory Improvement Amendments (CLIA) of 1988 final rule and in all 12 states that require licensure: California, Florida, Georgia, Hawaii, Louisiana, Montana, Nevada, New York, North Dakota, Rhode Island, Tennessee and West Virginia. 

An ABMM-certified medical microbiology laboratory director is medically, scientifically and administratively responsible for all that happens in the laboratory. The director aids the healthcare team by recommending appropriate testing options, assessing performance parameters for specific tests and applying appropriate guidelines for interpretation and reporting of test results. In doing so, the board-certified medical microbiology laboratory director is able to affect appropriateness, speed, cost-effectiveness and quality of patient care. With technology continuously expanding, and over 70 percent of medical decisions relying on laboratory testing, an ABMM-certified medical microbiologist offers a unique skillset for hospitals, healthcare systems, reference laboratories and industry as a key leader in navigating the ever-changing landscape of infectious disease diagnostics.

2021 Salary Survey

The ABMM conducted a salary survey in February 2021 to gather data so Diplomates have a resource for salary negotiations. The survey was sent to 490 ABMM Diplomates who resided in the U.S., and 206 responded (42% response rate). Drs. Yvette McCarter, D(ABMM), Chair, Gerald Capraro, D(ABMM), Sanchita Das, D(ABMM), Mark Gonzalez, D(ABMM), and Morgan Pence, D(ABMM) were assembled to analyze and summarize the data.
