摘要:
【Objective】 To study the feasibility of whole blood thromboelastogram (WB-TEG) and its correlative kit for plasma thromboelastogram (P-TEG) detection and the characteristics of P-TEG in healthy subjects. 【Methods】 17 healthy volunteers were detected by WB-TEG instrument and its correlative kit, and the results were compared with those by P-TEG. The P-TEG characteristics of 17 healthy volunteers were analyzed. Three groups (7 cases/group)of plasma samples with different platelet (Plt) count and the other three groups of plasma(7, 6 and 4 cases, respectively) with different fibrinogen(Fib) concentration were tested for P-TEG. The effects of Plt and Fib on P-TEG detection were observed. 【Results】 There was no significant difference in R and MA value (P>0.05)as WB-TEG was compared with P-TEG in healthy subjects, while in K(min) (1.71±0.47 vs 1.07±0.45), A(°) (66.1±5.41 vs 75.59±5.77), and CI value (0.9±1.8 vs 2.52±2.58)(all P <0.05). Various parameters of healthy individuals were basically within the range of 95% CI of WB-TEG, but there were significant diffferences in K, A and CI value(P<0.05). When Plt count (×1011/L) was≥2.5 in plasma, the MA value of P-TEG was significantly extended than that of normal individuals(P<0.05); when Plt count (×1011/L) was 6.0 ~12.0, the MA and CI value of P-TEG significantly decreased(P<0.05). When Fib(g/L) was 6.4~6.91 in plasma, the R and K value of P-TEG were prolonged, but A, MA and CI value all decreased(P <0.05); when Fib(g/L) <1, the A and MA value significantly decreased(P<0.05), and K and CI value could not be detected. 【Conclusion】 The WB-TEG and its correlative kit can be used in P-TEG detection, and corresponding reference values of TEG parameters should be established in combination with the conditions of laboratories.
