Clinical Laboratory

Dr. Gerlach's Laboratory

Human Lymphocyte Antigen (HLA) Testing
The tissue typing laboratory provides HLA typing for transplantation and HLA compatible platelets in support of the end stage renal and cardiac transplant programs in Grand Rapids, Michigan.  We also serve as a histocompatibility referral laboratory for several Michigan communities that are part of the Michigan State University College of Human Medicine campuses.

We provide molecular Class I and Class II HLA typing (low and high resolution), T and B cell Flow crossmatches, and HLA antibody identification by liquid bead microarray technology. The laboratory is Clinical Laboratory Improvement Act (CLIA) licensed, American Society of Histocompatibility and Immunogenetic (ASHI) accredited, and United Network of Organ Sharing (UNOS) approved and licensed by the Michigan Department of Community Health.

Dr. Gerlach is a member of the Biomedical Laboratory Diagnostics Program faculty, College of Natural Science and also a member of the College of Human Medicine faculty. Research projects revolve around transplant immunology, immunodiagnostics or molecular diagnostics.
