目的分析尿沉渣分析仪、尿沉渣镜检、干化学法对尿液红细胞、白细胞检验的临床应用价值。方法选取上饶市广丰区中医院2015年9—11月收治的行尿液检查患者500例,均采用尿沉渣分析仪、尿沉渣镜检、干化学法检测尿液红细胞、白细胞,比较3种检测方法的敏感性和特异度。结果尿沉渣镜检检测红细胞阳性110例、白细胞阳性89例,尿沉渣分析仪检测红细胞阳性140例、白细胞阳性124例,干化学法检测红细胞阳性138例、白细胞阳性116例。以尿沉渣镜检结果为金标准,尿沉渣分析仪检测红细胞敏感性、特异度与干化学法比较,差异无统计学意义(P>0.05);尿沉渣分析仪检测白细胞敏感性、特异度与干化学法比较,差异无统计学意义(P>0.05)。结论在临床工作中,尿沉渣分析仪、干化学法检测尿液方法简单、快速,但均具有一定的漏诊和误诊状况,临床可将尿沉渣分析仪、干化学法与尿沉渣镜检结合,可进一步提高诊断效果。
Objective To analyze the clinical value of urine sediment analyzer, urinary sediment microscopy and dry chemical method for urine red blood cells and white blood cells test. Methods 500 samples of urinalysis were collected from Guangfeng District Hospital of Traditional Chinese Medicine, Guangfeng District, Shanghai from September to November, 2015. Urinary sediment and white blood cells were detected by urinary sediment analyzer, urine sediment microscopy and dry chemical method respectively. Sensitivity and specificity of detection methods. Results Urine sedimentoscopy detected 110 cases of erythrocyte positive, 89 cases of leucocyte positive, urine sediment analyzer detected 140 cases of erythrocyte positive, 124 cases of leucocyte positive, dry chemistry test positive 138 cases of red blood cells, 116 cases of white blood cells positive. Urine sediment microscopy results as the gold standard urine sediment analyzer to detect erythrocyte sensitivity, specificity and dry chemical method, the difference was not statistically significant (P> 0.05); urine sediment analyzer to detect leukocyte sensitivity, specificity and Dry chemical method, the difference was not statistically significant (P> 0.05). Conclusions In clinical work, urinary sediment analyzer and dry chemical method for detecting urine are simple and rapid, but all have some misdiagnosis and misdiagnosis status. Urine sediment analyzer, dry chemistry and urinary sediment microscopy can be combined clinically, Can further improve the diagnostic results.
