光透射聚集测定法(LTA)作为体外血小板功能评估的“金标准”诊断试验，由于样本要求，其应用目前存在局限性。全血或多个电极aggregometry(MEA)使用多平台®分析仪(罗氏诊断)因其需要较小的血液量，减少样本比LTA操纵，现成为一个有吸引力的临床测试的选择。目前有关MEA与LTA在血小板聚集异常诊断中的直接比较较少。 研究人员纳入99例患者(66 F/33 M;中位年龄26岁[范围2‐

光透射聚集测定法(LTA)作为体外血小板功能评估的“金标准”诊断试验，由于样本要求，其应用目前存在局限性。全血或多个电极aggregometry(MEA)使用多平台®分析仪(罗氏诊断)因其需要较小的血液量，减少样本比LTA操纵，现成为一个有吸引力的临床测试的选择。目前有关MEA与LTA在血小板聚集异常诊断中的直接比较较少。

研究人员纳入99例患者(66 F/33 M;中位年龄26岁[范围2‐86]，作为黏膜皮肤出血初步实验室评估的参考，进行了平行MEA/LTA测试。在正常对照组中产生阈值反应的ADP、花生四烯酸(AA)、胶原蛋白和凝血酶受体‐活化肽(TRAP)的浓度用于检测患者。

结果显示，99例患者中，29例(30%)LTA至少有一次异常激动剂反应；其中15例患者>1激动剂反应异常。36例患者(36%)经MEA至少有1例异常激动剂反应；27例>1激动剂反应异常。MEA相对于LTA的敏感性/特异性:ADP, 0.70/0.72;AA,0.71/0.85；胶原蛋白,0.85/0.71；TRAP0.25/0.84。MEA相对于LTA的负预测值为：ADP, 0.90;AA,0.93;；胶原蛋白,0.97； TRAP,0.96。

研究表明，，MEA检测的特定异常结果不能充分预测在使用阈值激动剂浓度的LTA检测中特定异常。然而，有利的npv提示MEA可能有助于筛查患者血小板聚集异常；MEA结果正常，不需要进一步LTA诊断检测。
