Expected results of tests for hemostatic function in representative hemorrhagic disorders

Expected results of tests for hemostatic function in representative hemorrhagic disorders
Disorder Platelet count PT aPTT Fibrinogen
Vasculopathies, connective tissue diseases, or collagen disorders affecting skin normal normal normal normal or increased*
Thrombocytopenia low normal normal normal
Qualitative platelet abnormalities normal or low normal normal normal
Hemophilia A (factor VIII deficiency) normal normal long normal
von Willebrand disease normalΔ normal normal or long◊ normal
Disseminated intravascular coagulation low long long low
PT: prothrombin time; aPTT: activated partial thromboplastin time.
* Fibrinogen may be elevated as an acute phase reactant in disorders of inflammation.
¶ The platelet count in myeloproliferative disorders is usually high (eg, essential thrombocythemia) and platelets may also be qualitatively abnormal, predisposing to hemorrhagic and thrombotic diatheses.
Δ The platelet count may be low in some patients with type 2B von Willebrand disease.
◊ The aPTT may be normal in those with Factor VIII activity >40 percent.
