LOINC display name : HLA-DP & DQ & DR (class II) Ab.IgG low risk FC Nom;
LOINC long common name : HLA-DP and DQ and DR (class II) IgG low risk [Identifier] in Serum or Plasma by Flow
cytometry (FC);
LOINC short name : HLA class II Ab.IgG low risk SerPl FC;
LOINC 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 lower risk stratification of MFI values, but still detectable
and possibly having a risk of rejection (For one lab this range was 500 MFI 1999).;
