Coagulation is evaluated by conventional analyses, often supplemented by point-of-care tests. Currently, a number of point-of-care tests for evaluation of platelet function and the efficacy of antiplatelet therapy are being investigated. Thrombophilia contributes to the risk of thrombosis, and a battery of complex assays is required to identify all thrombophilias.

Disseminated intravascular coagulation (DIC) is characterized by microthrombosis and clinical bleeding. A scoring system for overt DIC provides a five-step diagnostic algorithm. The cornerstone of DIC management is treatment of the underlying triggering condition.

Heparin-induced thrombocytopenia (HIT) is an adverse immunological effect of heparin therapy. Besides thrombocytopenia, the major clinical consequence of HIT is an enhanced risk of thrombosis. The diagnosis is based on the clinical picture and detection of platelet-activating HIT antibodies. When HIT is strongly suspected, it is recommended to stop heparin treatment, order laboratory tests for HIT antibodies, and initiate nonheparin anticoagulant treatment.
