HLA-DP+DQ+DR (class II) IgG Ab [Presence] in Serum by Flow cytometry (FC)
Active
Term Description
IgG antibodies to HLA class II antigens (DP, DQ, and DR) can be detected by flow cytometry in serum of pre and post-transplant organ recipients. A positive result is an indication of a sensitization to HLA antigens. This code is based on, but not exclusive to, the submitter's test kit, One Lambda's FlowPRA Screening Test, which uses beads coated with common and rare purified HLA Class I or II antigens.

Part Description
LP156721-5 HLA-DP+DQ+DR Ab.IgG
The major histocompatibility complex (MHC) class I (A, B, and C) and II (DP, DM, DOA, DOB, DQ, and DR) in the human leukocyte antigen (HLA) system contains a large number of genes involved in immune system function in humans. The proteins encoded by some genes form antigens. HLA class I and II antigens are widely distributed on all nucleated cells and carried by platelets.
Antibodies specific to HLA class I and II antigens can be acquired through alloimmunization due to pregnancy, transfusion of blood products, or previous transplants. Alloimmunization can lead to production of antibodies in approximately one third of individuals. The presence of antibodies, specifically IgG, can affect the survival of transplant allografts or transfused platelets in sensitized individuals. Various testing methods are used to detect antibodies to HLA antigens.
