Term Description

Laboratories that perform HLA antibody testing often report the specific antibodies found in categories based on the "amount" of each antibody found (called mean fluorescent intensity, MFI, for the common Luminex bead method). Theoretically, the antibodies present in higher concentrations, which are more likely to react with donor antigens, will have higher MFI values. Since risk stratification based on MFI range is not standardized and the exact cutoffs vary from lab to lab, this term is intended to report those HLA antibodies found in the higher risk stratification of MFI values (For one lab this was MFI > 5000, but some laboratories use 10,000 or another value).

Part Description

LP417656-8   HLA-DP & DQ & DR (class II) Ab.IgG high risk
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. Source: Regenstrief LOINC
