94445-4
LaboratoryHLA-A IgG Ab [Identifier] in Serum or Plasma by Flow cytometry (FC)
Definition
This term will report antibodies detected against specific HLA antigens at the serologic type level. However, some high specificity assays,such as the Luminex single bead system, can detect epitopes at a more detailed molecular allele-equivalent level. Therefore, many laboratories using this assay will report, along with the serotype, the molecular type, and also the mean fluorescence intensity (MFI) in a single answer. This term is intended to cover the existing reporting formats for HLA-A antibody specificity.
