Reference values for kaolin-activated thromboelastography in volunteers of Anhui Province in China

BackgroundThe assessment of the coagulation status using thromboelastography (TEG) in Chinese population has less been reported. This study aimed to establish reliable reference values for kaolin-activated TEG in Chinese volunteers. MethodsA total of 1681 Chinese adult individuals were recruited for this study. The reference individuals were stratified by gender and age, and the TEG values were measured on the basis of strict quality control. The 95% reference values were determined using nonparametric statistical methods. ResultsThe sex-related 95% reference values were reaction time (R):4.2-8.7minutes; clotting time (K): 1.2-3.2minutes; alpha angle (): 47.0-72.3 degree; maximum amplitude (MA): 49.1-70.5mm for males, and R: 3.7-9.0minutes; K: 1.0-3.2minutes; : 48.4-74.4 degree; MA: 46.8-72.4mm for females. Also, the TEG parameters indicated a relatively more hypercoagulable profile in both female and elder groups. ConclusionsThis study established the reference values for kaolin-activated TEG in the target Chinese population, which might provide a reference for both clinical and laboratory studies.
