|---|---|---|---|
| name | Complement total hemolytic CH50 actual/normal in Serum by Immunoassay | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Complement total hemolytic CH50 actual/normal | ||
| property | RelACnc = Relative 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. | ||

History/Usage | |||
| first released | |||
| last updated | 2.58 | ||
| last change type | MIN - change to field other than name | ||
| change reason | Updated term to align with existing complement activity terms and clarify that findings are based on actual/normal results.; 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. | ||
