不同标本类型间髓过氧化物酶水平的检测分析

目的探讨不同标本类型间髓过氧化物酶(MPO)检测结果的差异性、抗凝剂的选择及检测结果的比对。方法同时采集165例健康体检人群含乙二胺四乙酸二钾(EDTA-K2)、肝素钠两种抗凝剂的血浆标本及不含抗凝剂的普通生化管的血清标本,分别检测3种标本类型中MPO水平,并对各组检测结果进行统计学分析。结果同一例体检者不同抗凝剂的血浆标本间及与不含抗凝剂的血清标本间MPO检测结果差异有统计学意义(P0.05)。结论不同标本类型对血液标本中MPO水平检测结果差异较大,建议各个实验室检测时根据不同抗凝剂制订相应的参考区间;由于EDTA-K2抗凝血浆不受体外白细胞中MPO释放的影响,推荐采用EDTA-K2抗凝血作为检测MPO水平的首选。

Detection and analysis of myeloperoxidase level in different types of samples

Objective To explore the difference of myeloperoxidase(MPO)detection results among different types of samples , anticoagulant selection and comparison of detection results .Methods The plasma samples containing EDTA‐K2 or heparin and ser‐um samples of common biochemical tube without containing anticoagulant were collected from 165 persons undergoing healthy physical examination .The MPO level in 3 kinds of sample was detected .Then the detection results in each group were performed the statistical analysis .Results The MPO detection results had statistical difference between plasma samples with different antico‐agulants and between plasma samples with different anticoagulants and serum sample without anticoagulant in the same person (P<0 .05) .Conclusion Different samples types have larger difference in M PO detection results .It is suggested that each laboratory should formulate the corresponding reference intervals according to different anticoagulants ;because EDTA‐K2 anticoagulation plasma is not affected by the release of MPO from in vitro leukocytes ,it is recommended to adopt EDTA‐K2 anticoagulation blood as the first selected of M PO level detection .
