Certification for professional medical technologists, laboratory technicians, physician office laboratory technicians and phlebotomy technicians  


Primary Purpose 

Attention Veterans:
The AAB Board of Registry (ABOR) examination fees for Medical Technologist - MT(AAB) and Medical Laboratory Technician - MLT(AAB) are approved for reimbursement under the G.I. Bill. For more information, visit:

The primary purpose of the AAB Board of Registry is to identify, on a non-discriminatory basis, those individuals who meet the minimum requirements for certification as an:

      • MT(AAB) – Medical Technologist  
      • ELS(AAB) – Embryology Laboratory Scientist
      • ALS(AAB) – Andrology Laboratory Scientist
      • MLT(AAB) – Medical Laboratory Technician
      • POLT(AAB) – Physician Office Laboratory Technician
      • PBT(AAB) – Phlebotomy Technician

These requirements do not discriminate against any individual or group of individuals on the basis of race, color, sex, religion, or source of national origin.  

Of the twelve states that require MTs and MLTs to pass a certifying or licensing examination, eleven recognize the AAB Board of Registry examinations: 

- California - Nevada
- Florida - North Dakota
- Georgia - Rhode Island
- Hawaii - Tennessee
- Louisiana - West Virginia
- Montana

 The other 38 states do not license MTs or MLTs. Instead, they use the CLIA '88 requirements.

[NOTE:  The State of Florida now recognizes the AAB Board of Registry’s Medical Technologist (MT) examinations in andrology, embryology and molecular diagnostics, in addition to the disciplines of Chemistry, Hematology, Immunology, Immunohematology, and Microbiology.]   

IMPORTANT:  Passing the AAB Board of Registry’s examinations may not be the only requirement for licensure in these states.  Individuals must also meet the state’s educational, training, experience, and continuing education requirements to qualify for state licensure.  Check with the state's clinical laboratory personnel licensing agency to obtain information specific to that state's licensure requirements.

The Mission of the AAB Board of Registry 

The AAB Board of Registry, since its inception in 1962, has championed the concept of a career ladder that includes “alternate routes” to formal academic degrees. 

In doing so, the AAB Board of Registry places more importance on having the requisite knowledge and skills than on where or how the knowledge and skills are obtained. 

Therefore, the AAB Board of Registry maintains alternate pathways for certification that permit individuals to qualify through a combination of formal education, training and experience. 

The AAB Board of Registry’s requirements for Medical Technologist (MT) are consistent with the CLIA requirements for individuals performing high complexity testing.
