摘要:目的 基于全自动凝血分析仪血小板聚集试验通道,建立表观健康人群血小板最大聚集率(MPAR)的参考区间。方法 募集表观健康人 134 例,采用 Sysmex CN3000 和 Sysmex CS5100 全自动凝血分析仪进行不同终浓度二磷酸腺苷(ADP)和花 生四烯酸(AA)诱导的血小板聚集试验检测。根据美国临床和实验室标准协会(CLSI)EP28A3c 文件,按照非参数法计算 MPAR 的参考区间。结果 不同终浓度 ADP 和 AA 诱导的 MPAR 重复性为 2.03% ~ 4.92%。不同终浓度 ADP 和 AA 诱导的 MPAR 在不同性别和年龄组之间差异均无统计学意义(P 均>0.05)。2 个检测系统各自 ADP 终浓度 2 和 5 μmol / L 之间、CS 系列 AA 终浓度 0.5 和 1.0 mmol / L 之间 MPAR 差异均有统计学意义(P 均<0.05)。除 AA 终浓度 1.0 mmol / L(Z = -2.319,P = 0.020),余不同终浓度诱导的 MPAR 在 2 个系统间差异均无统计学意义(P 均>0.05)。ADP 终浓度 2、5 和 10 μmol / L 诱导的 MPAR 生物参考区间在 CN3000 分别为 45.4% ~ 95.7%、72.0% ~ 94.3%和 76.3% ~ 95.1%,在 CS5100 分别为 45.3% ~ 93.7%、 73.1% ~ 99.1%和 75.9% ~ 97.6%;AA 终浓度 0.5 和 1.0 mmol / L 诱导的 MPAR 参考区间在 CN3000 分别为 72.1% ~ 95.7%和 81.0% ~ 95.9%,在 CS5100 分别为 77.1% ~ 96.9%和 81.1% ~ 99.5%。结论 本研究初步建立了 CN3000 和 CS5100 不同终浓度 ADP 和 AA 诱导的血小板聚集试验 MPAR 参考区间。
Abstract:Objective To establish a reference range for maximum platelet aggregation rate (MPAR)for the apparent healthy popula tion based on the platelet aggregation test channel in fullyautomated coagulation analyzers. Methods A total of 134 healthy adults were enrolled. Platelet aggregation tests induced by different concentrations of adenosine diphosphate (ADP)and arachidonic acid (AA)were performed on the fully automated coagulation analyzers,CN3000 and CS5100,respectively. According to the Clinical and Laboratory Standards Institute (CLSI)EP28A3c documents,the reference range of maximum platelet aggregation rates (MPAR)was established by the nonparametric method. Results The repeatabilities of ADP and AA induced MPAR with different final concentra tions were 2.03% to 4.92%. No significant difference of MPAR in different genders and ages was found (all P>0.05). There were sig nificant differences in the results of MPAR obtained using ADP at 2 and 5 μmol / L on the both systems,and using AA at 0.5 and 1.0 mmol / L on CS5100 system (all P<0.05). There was no significant difference for MPAR using the same concentration in the both test systems (all P>0.05)except using AA at 1.0 mmol / L (Z= -2.319,P= 0.020). The reference ranges of ADP induced MPAR with final concentration 2,5 and 10 μmol / L were 45.4% to 95.7%,72.0% to 94.3% and 76.3% to 95.1% on CN3000,and 45.3% to 93.7%,73.1% to 99.1% and 75.9% to 97.6% on CS5100,respectively. The reference ranges of AA induced MPAR with final concen tration 0.5 and 1.0 mmol / L were 72.1% to 95.7% and 81.0% to 95.9% on CN3000,77.1% to 96.9% and 81.1% to 99.5% on CS5100,respectively. Conclusion The reference ranges of MPAR in platelet aggregation tests induced by different final concentra tions of ADP and AA on automated coagulation analyzers CN3000 and CS5100 were preliminary established in this study.
