Heparin induced platelet IgG Ab in Serum or Plasma by Immunoassay
PF4 heparin cmplx IgG SerPl IA
Definition
- 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.
