Measles virus IgM Ab [Units/volume] in Body fluid by Immunoassay 74416-9
LOINC Code
| LOINC code | 74416-9 | ||
|---|---|---|---|
| name | Measles virus IgM Ab [Units/volume] in Body fluid by Immunoassay | ||
| description | Quantitative analysis of measles virus IgM antibodies in body fluid (e.g. mother's milk, lachrymal liquid, aqueous humor, etc.) is performed to aid in determining a patient's serological status to the measles virus. This term is based on, but not limited in use to, the LIAISON® Measles IgM assay, which uses chemiluminescence immunoassay (CLIA) technology for the quantitative determination of specific IgM antibodies to measles virus. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Measles virus Ab.IgM | ||
| 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 | Body fld = Body fluid, unspecified | ||
| 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. | ||

| last change type | MIN - change to field other than name | ||
| 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. | ||
