ABHI announces new content outline for the Histocompatibility and Immunogenetics Examinations. Applied Measurement Professionals (AMP) on behalf of ABHI distributed a practice analysis survey in 2011 and 2013 to all ASHI laboratories and associates, technologists, specialist and directors.

The practice analysis study was conducted to identify critical tasks performed by histocompatibility and immunogenetics professionals. The study results were intended to facilitate continued development of multiple-choice test forms.

These new outlines were introduced in the September 2014 administration of the Histocompatibility Associate, Specialist, Technologist and the Laboratory Director examinations.

The American Board of Histocompatibility and Immunogenetics (ABHI) is a certifying board offering voluntary credentialing examinations in the field of histocompatibility and immunogenetics. ABHI provides certification and promotes continuing education for histocompatibility and immunogenetics professionals. The Board is sponsored by the American Society for Histocompatibility and Immunogenetics (ASHI).

ABHI offers four levels of certification:

Certified Histocompatibility Associate: CHA(ABHI)
Certified Histocompatibility Technologist: CHT(ABHI)
Certified Histocompatibility Specialist: CHS(ABHI)
Diplomate of the ABHI D(ABHI)

ABHI also provides a process for granting formal recognition by means of certifying health care professionals working in histocompatibility and immunogenetics that have met professional standards. These individuals are examined at the pre and post-doctoral levels. By promoting consistency and quality of practice, ABHI assures the public that a certified individual has successfully completed the following: an approved educational program and an examination designed to assess knowledge, experience and skills.

ABHI evaluates and issues certificates of competency to successful applicants, provides a national standard that can be used to gauge professionalism, implements the educational and competency standards established by ASHI for laboratory personnel, defines and promotes laboratory work in histocompatibility and immunogenetics as an occupation in the public sector, promotes credentialing for histocompatibility testing professionals, promotes continued professional growth and documents such activities, maintains a registry of certified individuals and disseminates information by publications or other means.

Many see ABHI’s primary role as providing credentialing services to all levels of histocompatibility and immunogenetics professionals. Included in this process is the continual assessment and periodic updating of competency standards to reflect current laboratory practices. Another key function of ABHI is to encourage continuing certification by approving valuable CE credits in a cost-effective manner. By participating in ABHI-approved CE programs as a staff technologist, administrator, vendor or organization, you are promoting professional growth while enhancing knowledge. Together, these activities advance our work, serve our clients, and ultimately, improve patient care.
