Term Description

Heparin induced platelet (platelet factor 4, PF4) IgG antibodies are measured in optical density as part of an immunoassay. A OD value of >0.4 is considered an initial positive test. Additional heparin may be added to the patient's serum to determine percent inhibition by heparin (see LOINC 73817-9) and confirm a positive result.

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 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.
