摘要
目的：研究血液标本放置时间对生化检验结果的影响。方法以我院在2010年3月～2014年1月间收治的120例行生化检验的患者为研究对象，检测基准为1、4、8h后，分别实施生化检测，对7项检查结果进行分析，观察其具体的变化情况。结果检查基准为采血1h，血液标本放置时长达到4h后，从检查结果中可以看出，其血糖与谷丙转氨酶同标本放置1h内的检验结果存在显著差异，具有统计学意义（P＜0.05）。标本放置时间达到8h后，其总胆红素、碱性磷酸酶、钾离子、γ谷氨酰转肽酶、血糖与谷丙转氨酶与1h内的生化检测结果均存在显著差异，具有统计学意义（P＜0.05）。结论检测顺序的安排对于检测结果了产生较大影响，若检测项目具备不稳定因素，则测定工作需要在短时间内完成，可避免检测结果出现太大误差。
Objective To study the impact of blood specimen storage time on biochemical test results.Methods 120 patients admitted and treated in our hospital for routine biochemical tests from Mar 2010 to Jan 2014 were selected as research objects. The test baseline was set at 1 hour after blood specimen storage. Biochemical tests were conducted at 4 hours and 8 hours after blood specimen storage. 7 test results were analyzed to observe specific variations.ResultsThe test baseline was set at 1 hour after blood collection. After the blood specimen was stored for 4 hours, its test results had significant difference in blood glucose and glutamic-pyruvic transaminase with the results of same specimen stored for only 1 hour, with statistical significance （P〈0.05）. After the specimen was stored for 8 hours, its biochemical test results had significant difference in total bilirubin, alkaline phosphatase, potassium ion, gamma-glutamyl transpeptidase, blood glucose and glutamic-pyruvic transaminase with test results of same specimen stored for only 1 hour, with statistical significance （P〈0.05）.ConclusionArrangement of test sequence has significant impact on the test results. If the test item is instable, the test should be completed within a short period to avoid large deviation of the test results.
