Abstract    There is the important value with hemostasis and coagulation function tests in excluding diagnosis of venous thromboembolism (VTE), assisting diagnosis with thrombophilia, estimating risk of VTE and antithrombotics monitoring. The clinician should consider fully about population characteristics and drug influence before implementing the tests, and should understand with the major application rules of thrombosis tests, including (1) excluding diagnosis of VTE, to understand the diagnostic sensitivity with the D-dimer in the medical institution and ensuring safety and effectiveness; (2) the clinician should use different cut-off values for different population and aim of diagnosis and treatment; (3) it should understand the medical history and family history detailed before laboratory screening for patients with suspected genetic defects; (4) it should use the risk assessment model and pre-test probability to screen the patients which accord with test indications before lupus anticoagulant and heparin-induced thrombocytopenia antibody test performance.
