|---|---|---|---|
| name | Phospholipase A2 receptor IgG Ab [Units/volume] in Serum by Immunoassay | ||
| description | Phospholipase A2 Receptor (PLA2R) antibodies in human serum can be quantitatively measured in relative units (rU) by immunoassays. Such antibodies are found in patients with idiopathic membranous glomerulonephritis (MGN) but not in patients with secondary glomerulonephritis. The test is used to differentiate these two conditions. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Phospholipase A2 receptor Ab.IgG | ||
| property | ACnc = Arbitrary Concentration | ||
| 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 = Serum | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
| method | IA = Immunoassay: Encompasses all immunoassays with a few exceptions, including Immune Blot and Immune Fluorescence, which were created based on historic usage. | ||
Additional Names | |||
| short name | PLA2R IgG Ser IA-aCnc | ||

Associated Observations | |||
LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations. | |||

| change reason | The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016. | ||
