Change Reason
Release 2.69: DefinitionDescription: Removed reference to QuantiFERON-TB assay from the description because this term is not specific for that assay.; Previous Releases: 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.
