The Immunogenetics Laboratory provides testing to support solid organ transplantation by performing human leukocyte antigen (HLA) typing for donors and recipients, HLA antibody testing to identify anti-HLA antibodies and flow crossmatches to assess donor-recipient compatibility. In addition, Nevadan Donor Network also performs and interprets antibody screens for Donor Specific Antibodies (DSA) after transplant.

As the only HLA laboratory in the State of Nevada, the HLA team provides testing for the University Medical Center for Transplantation of Southern Nevada (UMCSN) as well as our clients in Arizona and California.

The HLA laboratory is accredited by American Society of Histocompatibility and Immunogenetics (ASHI), certified by CLIA and licensed by the State of Nevada for high-complexity testing.
