Combination Of 4T's Score and Rapid Gel Centrifugation Assay Excludes HIT In a Prospective Cohort Study

Abstract The diagnosis of heparin-Induced thrombocytopenia (HIT) is based on the presence of a compatible clinical picture combined with laboratory evidence of heparin-dependent, platelet-activating IgG antibodies. The 4T's Score is a clinical prediction rule that determines the likelihood that a patient has HIT before laboratory testing is performed.
