Change Reason
Changed Component core from "Platelet factor 4 polyanion (PVS) complex" to "Platelet factor 4 heparin complex induced" to align the Component for the newer terms with the existing older terms (the meaning is the same).; 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 System from "Ser" to "Ser/Plas" since this test can be performed on either serum or plasma.
Order vs. Observation
