| description | Sometimes high titer antibody can be associated with low levels of detection (low mean fluorescence intensity, MFI, for the Luminex HLA bead assay), a phenomenon often referred to as the "prozone" effect. This term is intended to report those antibodies that were not detected at significant level with original sample, but became detectable after dilution or assay treatment. Some laboratories refer to these "prozone antigens observed", meaning those antigens for which the patient's antibody exhibited prozone effect. | |
| status | ACTIVE | |
Fully-Specified Name | ||
| component | HLA-DP & DQ & DR (class II) Ab.IgG with prozone effect | |
| 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. | |
| method | Flow cytometry | |
