摘要
目的分析血液分析仪测定血小板计数的相关影响因素,排除假性降低以及假性增高情况以后得到的准确血小板计数水平。方法选取2011年1月—2012年12月我院收治的300例患者,均采用XE-1000i全自动血细胞分析仪测定,对不在血液分析仪阈值范围内的标本改行手工复检测定。结果 300例患者标本根据血小板计数分为患者A、患者B、患者C,每组各100例,仪器法组与手工法组的差异随血小板计数的减少而逐渐增大,差异有统计学意义(P<0.05);仪器法组与手工法组血标本放置的时间不同血小板计数比较差异有统计学意义(P<0.05)。结论对于血液分析仪测定血小板计数结果不在阈值范围内的标本病例应采用手工复检测定,并保证血标本的方式时间<120min。
Objective To analyze the effect factors of influence of detecting platelets by hematology analyzer to remove falsely lower and falsely higher to get the correct PLT.Methods Choosed data of 300 patients from Jan.2011 to Dec.2012 to analyze PLT by XE-1000i hematology analyzer.Results There were PLT of 100 cases beyond the scope of threshold value to manual review.There was significant difference between hematology analyzerm and manual test（P 0.05）.And the longer the specimen placed time,the lower the results were.And there was significant difference of resutls between detecting in 0 min and 120 mins（P 0.01）.Conclusion We should manual review results of PLT dectecting by hematology analyzer beyond the scope of threshold value and ensure detecting time in 120 mins.
