| name | HLA-A and B and C (class I) IgG high risk [Identifier] in Serum or Plasma by Flow cytometry (FC) | ||
| 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). | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | HLA-A & B & C (class I) Ab.IgG high risk B = Buccal | ||
| property | Prid = Presence or identity: Prid stands for “Presence or identity”, is used for assays that detect whether or not an analyte of a particular kind is present, and if it is, to identify the specific analyte. | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser/Plas Ser = Serum Plas = Plasma | ||
| scale | Nom = Nominal: Nominal or categorical responses that do not have a natural ordering. (e.g., names of bacteria, reported as answers, categories of appearance that do not have a natural ordering, such as, yellow, clear, bloody. | ||
