77684-9Legionella pneumophila 1 Ag [Presence] in Urine by Rapid immunoassayActive

Term Description

For patients with symptoms of pneumonia, this test allows for early diagnosis of Legionella pneumophila serogroup 1 infection by detecting a specific soluble antigen present in the urine of patients with Legionnaires Disease. This term was created for, but not limited in use to, the submitter's Alere BinaxNOW Legionella Urinary Antigen Card test kit, which is a immunochromatographic membrane assay. Once reagents and cards are at room temperature, the test results can be read in about 15 minutes.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; 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.
