The human leukocyte antigen (HLA) system consists of a complex array of genes.
HLA antigens are found on the surface membranes of all nucleated cells of the
body, including solid tissues, lymphocytes, granulocytes, monocytes, and platelets.
The antigens of the HLA system are involved in the rejection of transplanted solid
organs, bone marrow and the survival of platelet transfusions. Many HLA antigens
have been identified. The NYBC HLA-testing laboratory does HLA typing of individuals
and families for the A, B, C and DR genetic loci, as well as HLA antibody screening
of leukocytes and platelets.
