摘　　要：目的研究在不同阶段开展临床微生物标本检验对微生物标本检验阳性率的影响。方法本文于2018年4月至2019年10月开展调查工作,选择在此期间到我院进行身体检查的200例体检者作为研究对象,所有研究对象分别在上午(6:01~11:00)、中午(11:01~13:00)、下午(13:01~18:00)、夜间(18:01~6:00)不同时间段采集相关的标本(包括痰液标本、血液标本、尿液标本、大便标本和腹水标本等)开展检验。对不同阶段的不同标本微生物的检验结果进行统计和比较。结果①痰液标本夜间检出的阳性率最高,中午检出阳性率最低,上午检出结果最接近实际值,相互比较,差异有统计学意义(P<0.05)。②血液标本夜间检出阳性率最高,下午检出阳性率最低,上午检出阳性率接近实际值,相互比较,差异有统计学意义(P<0.05)。③尿液标本夜间检出阳性率最高,中午检出阳性率最低,上午检出结果最接近实际值,相互比较,差异有统计学意义(P<0.05)。④大便标本夜间检出阳性率最高,中午检出阳性率最低,上午检出结果最接近实际值,相互比较,差异有统计学意义(P<0.05)。⑤腹水标本夜间检出阳性率最高,中午检出阳性率最低,上午检出结果最接近实际值,相互比较,差异有统计学意义(P<0.05)。结论临床采集标本微生物的时间段不同,检验出的阳性结果也存在一定的差异。上午为最佳的标本微生物采集时间段,其检出值更为准确。所以检验工作应尽可能在此阶段采集研究对象的微生物标本送检,这能提高整体检验的准确性。Objective To study the effect of carrying out clinical microbiological specimen testing at different stages on the positive rate of microbiological specimens.Methods This article carried out investigation work from April 2018 to October 2019.During this period,200 people who came to our hospital for physical examination were selected as the research objects.All the research objects were in morning(6:01-11:00),noon(11:01-13:00),afternoon(13:01-18:00),night(18:01-6:00)relevant specimens(including sputum specimens,blood specimens,urine specimens),stool specimens,ascites specimens,etc.)to carry out inspections.Statistic and compare the microbiological test results of different specimens at different stages.Results(1)The positive rate of sputum specimens was the highest at night and the lowest at noon.The results in the morning were the closest to the actual value.Compared with each other,the difference was statistically significant(P<0.05).(2)Blood specimen the positive rate was the highest at night and the lowest in the afternoon.The positive rate in the morning was close to the actual value.Compared with each other,the difference was statistically significant(P<0.05).(3)The urine specimen was the highest at night,the positive rate of detection at noon was the lowest,and the detection result in the morning was closest to the actual value.Compared with each other,the difference was statistically significant(P<0.05).(4)The positive rate of stool specimens was the highest at night,and the positive rate was the lowest at noon.The detection result in the morning was the closest to the actual value,and compared with each other,the difference was statistically significant(P<0.05).(5)Ascites specimens had the highest positive rate at night,the lowest positive rate at noon,and the morning results were closest to the actual value,compared with each other,the difference was statistically significant(P<0.05).Conclusion The time period of clinical collection of microbes is different,and the positive results of the test also have
