Brief summary: The purpose of this study was to establish the normal reference range of Thrombelastogram parameters in Hunan by a multicenter study, and to analyze the specificity of Thrombelastogram detection and the influence of gender, age and blood type on Thrombelastogram. The study will provide basic data and statistical basis for the establishment of normal reference range of Thrombelastogram in Hunan.

Detailed description: Thrombelastograghy (TEG) is an important test to assess the blood coagulation function to monitor the whole process of perioperative coagulation. TEG can evaluate the coagulation cascade, from platelet aggregation, clot strengthening and fibrin cross-linking to eventually clot lysis in small volume of whole blood. The reference range is one important element to influence the TEG results. At present, a number of studies have shown that reference range of TEG exists significant differences between different racial and geographic. At the same time, reagent manufacturers also suggested that each TEG laboratory should establish its own reference range. So it is important to establish our own reference range of TEG to guide the clinical blood transfusion and treatment.

Eligibility criteria: Inclusion Criteria:

(1) 18\< Age \<65, and Han Chinese residents living in Hunan more than 3 years. (2) Health examination population who physical examination, assistant examination and serological examination were normal; Not suffer from other diseases last 3 months; Not take any medication last 7 days.

Exclusion Criteria:

1. Informed refusal. 2. Pregnancy, woman with menstrual period; volunteers who suffer from hematological system diseases such as hemorrhagic or thrombotic disease and take medicines that affect the function of blood coagulation (clopidogrel and aspirin, warfarin, rivaroxaban, dipyridamole, oral contraceptives, estrogen, antibiotics and traditional Chinese medicine related with blood coagulation, etc.) 3. Volunteers who have a history of liver disease, immune system disease, allergy and other disease within the last 3 months were excluded.
