LOINC display name : Percent heparin inhibition (S) [Ratio];
LOINC long common name : Percent heparin inhibition [Ratio] in Serum;
LOINC short name : Prcnt hep inhibited Ser-Rto;
LOINC description : The percent inhibition by heparin is determined by adding excess heparin (high-dose
heparin) to the patient's serum. Testing is performed to increase the specificity
of the assay and confirm a positive heparin induced antibody result. Inhibition of
a positive result by 50% or more reduction in the optical density is considered confirmatory
and characteristic of Type II heparin induced thrombocytopenia (HIT) antibodies.;
