摘要:

目的 探讨血液标本放置时间对部分心血管疾病相关生化指标的影响。方法 选取80例进行常规生化检测的患者,每例患者抽取6管血液标本,将其中1管用移液器将血清吸出加入4支冻存管中,分别于即刻、2~8 ℃冷藏过夜及-20 ℃冷冻24、72 h后检测,另外3管于室温分别放置1、3、6 h后检测,剩余2管先在室温下放置6 h,随后分别于-20 ℃冷冻24和72 h后检测。检测项目包括缺血修饰白蛋白(IMA)、乳酸脱氢酶(LDH)、天门冬氨酸氨基转移酶线粒体同工酶(m-AST)、游离脂肪酸(FFA)。分析放置不同时间的血标本各项目检测结果的差异。结果 与即刻检测结果比较,室温放置1 h后LDH、FFA呈升高趋势,m-AST、IMA呈降低趋势,但差异无统计学意义(P>0.05);2~8 ℃冷藏过夜及室温放置3和6 h后LDH、FFA明显升高(P<0.05),m-AST、IMA明显降低(P<0.05),6 h后LDH、FFA升高更为明显(P<0.01)。即刻分离血清并-20 ℃冷冻24、72 h后的LDH、FFA、m-AST和IMA检测结果与即刻检测结果比较,差异均无统计学意义(P>0.05)。与即刻检测结果比较,室温放置6 h后再-20 ℃冷冻24、72 h的LDH、FFA检测结果均明显升高(P<0.01),m-AST、IMA均明显降低(P<0.01)。结论 血液标本长时间放置会对LDH、FFA、m-AST、IMA的检测结果产生明显影响。

Abstract:

Objective To investigate the influence of different placed times of blood specimens on some biochemical indicators of cardiovascular disease related determination. Methods A total of 80 patients undergoing routine biochemical determination were enrolled,and every patient was extracted for 6 tubes of blood specimens. Serum of 1 tube was extracted by pipette and divided into 4 cryovials,which were determined immediately,after 2-8 ℃ refrigerated overnight,after -20 ℃ refrigerated for 24 h and after -20 ℃ refrigerated for 72 h. The other 3 tubes were determined after being placed at room temperature for 1,3 and 6 h,while the other 2 tubes were placed at room temperature for 6 h,and were determined after -20 ℃ refrigerated for 24 and 72 h. Ischemia modified albumin(IMA),lactate dehydrogenase(LDH),aspartate aminotransferase isoenzyme(m-AST) and free fatty acid(FFA) were determined. The difference of different placed times of blood specimens on some biochemical indicators of cardiovascular disease related determination was evaluated. Results Compared to the results of those determined immediately,LDH and FFA increased,while m-AST and IMA decreased in those determined after being placed at room temperature for 1 h(P>0.05). As for those determined after 2-8 ℃ refrigerated overnight and those determined after being placed at room temperature for 3 and 6 h,LDH and FFA increased(P<0.05),m-AST and IMA decreased(P<0.05),and LDH and FFA for 6 h were higher than those for 3 h(P<0.01). The results of those determined after -20 ℃ refrigerated for 24 and 72 h had no statistical significance compared with those determined immediately(P>0.05). The results of those determined after being placed at room temperature for 6 h and determined after -20 ℃ refrigerated for 24 and 72 h were higher than those determined immediately(P<0.01),and m-AST and IMA decreased(P<0.01). Conclusions Long placed times of blood specimens have influence on some biochemical indicators of cardiovascular disease related determination.
