摘要
目的探讨尿液干化学与尿有形成分分析显微镜复检的差异性。方法选取2021年4—7月该院查体中心化验室进行尿检的新鲜中段尿液标本413份,对其进行尿有形成分分析、尿液干化学法与显微镜检测。将显微镜复检结果作为金标准,评价尿液干化学法、尿有形成分分析与尿液干化学法联合尿有形成分分析对于该组尿液标本的诊断结果,以及对于该组尿液标本白细胞、红细胞阳性诊断的灵敏度、特异度、阴性预测值、阳性预测值与符合率。结果该组413份尿液标本经显微镜复检结果检测白细胞阳性125例(30.27%),阴性288例(69.73%);红细胞阳性120例(29.06%),阴性293例(70.94%)。尿液干化学法联合尿有形成分分析对尿液标本白细胞检测的灵敏度94.40%、特异度95.83%、阴性预测值97.53%、阳性预测值90.77%、准确率95.40%均高于单纯尿有形成分分析72.00%、91.32%、88.26%、78.26%、85.47%,差异有统计学意义(χ^(2)=22.436、4.881、18.605、7.446、39.341,P<0.05),以及尿液干化学法68.00%、90.28%、86.67%、75.22%、83.54%,差异有统计学意义(χ^(2)=28.535、6.878、23.172、10.627、47.749,P<0.05)。尿液干化学法联合尿有形成分分析对尿液标本红细胞检测的灵敏度95.83%、特异度97.27%、阴性预测值98.28%、阳性预测值93.50%、准确率96.85%均高于单纯尿有形成分分析72.50%、92.15%、89.11%、79.09%、86.44%,差异有统计学意义(χ^(2)=24.513、7.664、20.762、10.447、29.240,P<0.05),以及尿液干化学法68.33%、91.47%、87.58%、76.64%、84.75%,差异有统计学意义(χ^(2)=30.854、9.280、25.437、13.237、36.228,P<0.05)。结论尿液干化学与尿有形成分分析联合检测尿液成分能够提高检测结果的准确性。
Objective To explore the difference between urine dry chemistry and microscopic reexamination of urine sediment analysis.Methods Selected 413 fresh mid-section urine specimens from April to July 2021 in the central laboratory of the hospital for urinalysis.Urine formed component analysis,urine dry chemistry and microscopy were performed.The results of the microscopic reexamination were used as the gold standard to evaluate the diagnostic results of urine dry chemistry method,urine formed component analysis and urine dry chemistry method combined with urine formed component analysis for this group of urine specimens,and the sensitivity,specificity,negative predictive value,positive predictive value and coincidence rate of the positive diagnosis of white blood cells and red blood cells in this group of urine samples.Results In this group of 413 urine specimens,125 cases(30.27%)were positive for white blood cells and 288 cases(69.73%)were negative by microscopic reexamination;120 cases(29.06%)were positive for red blood cells,and 293 cases(70.94%)were negative.The sensitivity of urine dry chemistry combined with urine formed element analysis for the detection of white blood cells in urine samples was 94.40%,specificity 95.83%,negative predictive value 97.53%,positive predictive value 90.77%,and accuracy rate of 95.40%.They were all higher than the simple urine formed component analysis of 72.00%,91.32%,88.26%,78.26%,85.47%,and the difference was statistically significant(χ^(2)=22.436,4.881,18.605,7.446,39.341,P<0.05).And urine dry chemical method 68.00%,90.28%,86.67%,75.22%,83.54%,and the difference was statistically significant(χ^(2)=28.535,6.878,23.172,10.627,47.749,P<0.05).Urine dry chemistry combined with urine formed component analysis had 95.83%sensitivity,97.27%specificity,98.28%negative predictive value,93.50%positive predictive value,and 96.85%accuracy for the detection of red blood cells in urine specimens.All higher than the simple urine formed analysis 72.50%,92.15%,89.11%,79.09%,86.44%,and the differe
