血液标本不同放置时间对生化检验的结果影响探讨

目的分析血液标本不同放置时间对于生化检验结果的影响。方法采用BT3000全自动生化分析仪和IMS-972电解质分析仪,收集放置1h、3h、6h、24h后的血液标本,分别检测11项常规生化指标。结果标本放置3h结果有显著性差异的项目是GLU;放置6h结果有显著差异的是GLU、BUN、K＋;放置24h时间结果有显著差异项目有K＋、Na＋、CL-、Ca2＋、BUN、Cr、GLU、ALT、AST、ALP、GGT。结论标本放置时间对生化检测结果有影响,考虑到试验允许误差,检测血糖应在血液标本放置3h内完成;电解质测定特别是K＋的检测应在血液标本放置6小时内完成。

The Influence of Different Disposing Time on Biochemical Test Results of Blood Samples

Objective To analyze the influence of different disposing time on biochemical test results of blood samples. Methods BT3000 automatic biochemical analyzer and IMS-972 electrolyte analyzer were used to detect 11 biochemical indices of blood samples deposited 1 h, 3 h, 6 h, 24 h respectively. Results The item of 3 h deposited samples that had significant difference was GLU; the items of 6 h deposited samples that had significant difference were GLU, BUN, K＋; the items of 24 h deposited samples that had significant difference were K＋, Na＋, CL-, Ca2＋, BUN, Cr, GLU, ALT, AST, ALP, GGT. Conclusion The disposing time of blood samples has influence on biochemical test results. The GLU detection should be taken within 3 h, the electrolyte detection especially K＋ should be taken within 6 h.
