Sysmex XT-2000i血液分析仪血小板聚集报警信息评价

目的通过检测血小板最大聚集率结合SysmexXT-2000i血液分析仪提示的“PLT Clumps？”判断信息，对Sysmex XT-2000i血液分析仪血小板聚集报警信息进行评价。方法对345例患者用Sysmex XT-2000i血液分析仪进行分析，同时用比浊法检测血小板最大聚集率，对结果进行比较和统计分析。结果血液分析仪血小板聚集报警阳性组血小板最大聚集率明显高于阴性组（P〈0．05），两种方法对血小板聚集活性判断结果存在一定的一致性（Kappa值=0．61）。结论Sysmex XT-2000i血液分析仪血小板聚集报警信息有一定的可靠性，对血小板聚集功能的初步判断提供一定的依据。

Performance Evaluation of Sysmex XT-2000i Hqematology Analyzer in Platelet Aggregation Function

Objective To evaluate sysmex XT-2000i automated haematology analyzer in analysis of platelet aggregation according to the ＂PLT lumps？＂ and measurement of maximum platelet aggregation rate. Methods 345 patients were analyzed by sysmex XT-2000i and plasma maximum platelet aggregation rate（MAR） was detected. The results were compared and analyzed statistically. Results Platelet aggregation rate of positive group judged by sysmex XT-2000i was significant higher than negative group（P〈0. 01）,and the two methods of evaluating platelet aggregation function had certain dependability （Kappa-=0. 61）. Conclusion The information proved in the platelet detecting process of sysmex XT- 2000i may provide certain basis to preliminary analysis judgment of the platelet aggregation function.
