Part Descriptions

LP14307-0   HIV 1
Human immunodeficiency virus is a non-taxonomic and historical term referring to any of two species, specifically HIV-1 and/or HIV-2. Prior to 1986, this was called human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). From 1986-1990, it was called HIV and since 1991, the two species have been designated HIV-1 and HIV-2. Source: National Library of Medicine, MeSH 2006

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.; Updated Answer list type from NORMATIVE to EXAMPLE because the Answers in the list (Positive, Negative) are only examples of possible answers and not an exclusive list
Order vs. Observation
Both
