[Diagnosis of hemorrhagic diseases (author's transl)].
Bleeding symptoms require in many instances immediate professional care. In order to avoid unnecessary treatment, an exact diagnosis is mandatory. In most cases a differentiation between primary humoral and thrombocytogenic bleeding disorders and a secondary bleeding diathesis due to consumption coagulopathy is possible by means of anamnestic, clinical and laboratory parameters. As a single test, the bleeding time gives the best information, followed by the heparin-tolerance-time, the PTT and the platelet count. Withe Quick-test alone, only 5% of children with severe bleeding diathesis are detected. For preoperative laboratory evaluation we recommend a combination of PTT, Quick-test, platelet count and bleeding-time. For the diagnosis of disseminated intravascular coagulation, anamnestic criteria (procoagulant triggers) and clinical evaluation [thrombohemorrhagic syndrome of organ(s)] are as important als laboratory parameters (platelet count, plasminogenproactivator, splits, PTT, Quick-test).
