溶血标本对48项生化检验结果的影响

目的探讨标本溶血对生化检验结果的影响,为检验人员和临床医生对溶血标本的生化检验结果进行正确的分析提供依据。方法取未溶血标本的血清进行48项生化项目检验,然后经搅拌使标本发生轻度溶血、中度溶血、重度溶血,3 000r/min离心10min,进行相同的生化项目检验,对未溶血、轻度溶血、中度溶血及重度溶血标本的检验结果进行统计分析。结果轻度溶血血清测定中共有16项结果与未溶血标本比较差异有统计学意义(P0.05);中度溶血与未溶血标本检验结果的比较有25项差异有统计学意义(P0.05);重度溶血标本检验有28项结果与未溶血标本比较差异有统计学意义(P0.05)。结论标本溶血对大部分生化检验项目的结果可产生显著性影响,在生化检测分析中遇到标本溶血但又必须报告时应在报告单上注明,提醒医师和患者引起注意;分析引起标本溶血的原因,避免溶血现象的发生,保证检验结果的真实、准确。

Analysis on influence of hemolytic samples on 48-item biochemical test resuts

Objective To discuss the influence of sample hemolysis on the biochemical testing results to provide the basis for the laboratory personnel and clinical doctors correctly analyzing the biochemical testing results of hemolytic samples .Methods Serum from non‐hemolytic samples was taken and performed the detection of 48 biochemical items .Then the sample was stirred for indu‐cing the mild ,moderate and severe hemolysis .Centrifugation was conducted at 3 000 r/min for 10 min .Finally the detections of the same biochemical testing items were performed again .The detection results of non‐hemolysis ,mild ,moderate and severe hemolysis samples were statistically analyzed .Results As compared with the non‐hemolytic samples ,the 16‐item detection results in the mild hemolysis samples showed statistically significant difference ,25‐item detection results in the moderate hemolysis samples showed statistically significant difference and 28‐item detection results in the severe hemolysis samples showed statistically significant difference (P<0 .05) ,respectively .Conclusion The sample hemolysis could produce the significant influence on the majority of bi‐ochemical testing items .Therefore ,the sample hemolysis is encountered and the detection results must be reported in the biochemi‐cal detection ,the clear indication should be given in the report for reminding the doctor and patient to arouse attention .The causes leading to the sample hemolysis should be analyzed for avoiding the occurrence of hemolysis phenomenon and ensuring the truthfull‐ness and accuracy of the detection results .
