Term Description

This term was created for, but not limited in use to, the submitter's Alere TestPack Plus Strep A test kit, which uses a rapid immunoassay for the detection of Group A Streptococcal antigen. The kit needs to come to room temperature if refrigerated (30 minutes specified), then 2- 5 minutes to perform.

Part Description

LP15188-3   Streptococcus pyogenes
Streptococcus pyogenes, also known as Group A Streptococcus (GAS), is a species of gram-positive, coccoid, beta-hemolytic bacteria. It is responsible for a wide variety of both invasive and non-invasive diseases including scarlet fever, pharyngitis, impetigo, cellulitis, necrotizing fasciitis and toxic shock syndrome, as well as the sequelae of rheumatic fever and acute poststreptococcal glomerulonephritis. Invasive GAS infections can be associated with very high mortality rates. [PMID:26866208] Source: Regenstrief LOINC

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.
