目的:分析血标本放置时间和方式对9项生化指标检测结果的影响。方法:选择该院2014年1~12月之间126例接受血清生化检验患者的血清标本,取患者空腹静脉血8 ml,取其中2 ml立刻进行离心处理并进行检验;另外的6 ml血液分别放置于甲、乙、丙三个试管中。结果:对比对照组,甲组样本中除ALB与CK指标之外均出现明显下降;乙组样本保存2 h之后的氯离子浓度下降,12 h后钾离子浓度上升,24 h之后LDH、AST等指标上升;丙组试管冻存1 w之后除ALB、AST与GLU指标外,其余指标均有明显改变。结论:血标本放置时间和方式对9项生化指标检测结果均具有一定程度的影响。
OBJECTIVE: To analyze the effect of blood sample placement time and method on the detection results of 9 biochemical indexes. Methods: A total of 126 serum samples from patients receiving serum biochemical tests from January to December 2014 in our hospital were collected. 8 ml fasting venous blood samples were collected from patients and 2 ml samples were immediately centrifuged and tested. The other 6 ml blood samples Placed in A, B, C three test tubes. Results: Compared with the control group, the samples of Group A showed a significant decrease except for ALB and CK. The concentration of chloride ion in Group B decreased after 2 h, and the concentration of potassium increased after 12 h. After 24 h, LDH and AST Indicators increased; Group C after 1 w frozen tube except ALB, AST and GLU indicators, the other indicators were significantly changed. Conclusion: The time and method of blood sample placement have certain influence on the detection results of 9 biochemical indexes.
