Heparin-induced thrombocytopenia in solid organ transplant recipients: The current scientific knowledge

Figure 1 The frequency of antibody seroconversion, activating heparin-induced thrombocytopenia antibodies (serotonin release assay/heparin induced platelet activation assay), thrombocytopenia, and clinically manifest heparin-induced thrombocytopenia thrombotic syndrome are illustrated as an “iceberg”[4,9,10]. The waterline indicates the threshold between positive laboratory findings and clinical appearance of HIT. HIT: Heparin-induced thrombocytopenia.
