摘要
通过对肝功能储备分析仪探头的测试,评价其检测功能的精确度,以保证肝功能储备分析仪检测结果的准确性及有效性。利用探头对吲哚菁绿药物浓度的探测敏感性,对稀释后不同浓度的吲哚菁绿进行检测并将检测结果与实际吲哚菁绿浓度进行对比,以此验证探头的精确性。经过对比发现,在理想试验状态下,使用2年以内探头的检测精确度误差小于0.5%,使用2~4年探头的检测精确度误差约1%,使用4年以上探头的检测精确度误差大于2%。为了保证肝功能储备分析仪检测结果的准确性与有效性,使用2年以内的探头应每年检测1~2次,使用2~4年的探头应每年检测2~4次,使用4年以上的探头应每月检测1次或直接更换新探头。
By testing the probe of the liver function reserve analyzer,the accuracy of its detection function is evaluated to ensure the accuracy and validity of the detection results of the liver function reserve analyzer.Using the probe's detection sensitivity to the concentration of indocyanine green drugs,detect different concentrations of indocyanine green after dilution and compare the detection results with the actual concentration of indocyanine green to verify the accuracy of the probe.After comparison,it is found that under ideal test conditions,the detection accuracy error of the probe within 2 years is less than 0.5%,the detection accuracy error of the probe using 2-4 years is about 1%,and the detection accuracy error of the probe using morethan 4 years is greater than 2%.In order to ensure the accuracy and validity of the test results of the liver function reserve analyzer,the probe used within 2 years should be tested 1-2 times a year,the probe used for 2-4 years should be tested 2-4 times a year,and the probe used for more than 4 years The probe should be tested once a month or directly replaced with a new probe.
