尿液分析仪检验血尿在法医学中应用研究

尿液分析仪检验血尿在法医学中的应用价值。应用尿液分析仪干化学法及尿沉渣显微镜法对 418例患者尿样红细胞成份同时进行检测 ,结果表明 ,尿液分析仪检验结果 :阴性 2 76例、“ +” 5 8例、“ ++” 35例、≥“ ++” 84例 ,尿沉渣镜检法相应程度的检验结果分别为阴性 2 74例、“ +-”和“ +” 31例、“ ++” 1例、≥“ ++” 37例 ,相同的程度符合率分别为 99 2 6 %、 5 3 45 %、 2 86 %、 44 0 5 %。两法阳性与阴性结果及轻伤程度 (≥ ++)与轻微伤程度 (≤ +)结果比较均有高度显著性差异 (P <0 0 1)。尿液分析仪检验阳性率高于尿沉渣镜检法 ,且表现血尿程度略严重。尿液分析仪检验结果阴性和“ +”与尿沉渣镜检法 0～ 3/HP (阴性或少许 )程度一致 ,属正常范围。目前 ,法医学鉴定中用尿液分析仪检验结果 2 5 / μl ( ++)相当于尿沉渣镜检法红细胞 10～ 30 /HP ( ++) ,引用《人体轻伤鉴定标准 (试行 )》第 36条进行法医学鉴定是不准确的 ,不能将尿液分析仪完全替代尿沉渣镜检法用于法医学鉴定

Evaluation of the hematuria examination by urinary analyzer in forensic medicine practice

The role of the hematuria examination by urinary analyzer in forensic medicine practice was evaluated in the present study.By using the chemical analysis of urinary analyzer and urinary sediment microscopy,the erythrocytes in 418 urine samples were examined simultaneously.The results showed that the negative outcome was found in 276 cases,+ in 58,++ in 35,≥++ in 84 by urinary analyzer,while negative outcome in 274 cases, +- and + in 31, ++ in 1 ,≥++ in 37 with consistent rates of 99 26%, 53 45%, 2 86% and 44 05% respectively.There was high significant difference between the positive and negative outcome and between the trauma mild (≥++) and slight trauma outcome (≤+) as determined by these two methods ( P <0 01).The positive rate by urinary analyzer examination was higher than that by the urinary sediment microscopy.The negative or + outcome by urinary analyzer examination was consistent with 0～3/HP(negative or less)by urinary sedimentation microscopy.It is wrong that the outcome of 25/μl as determined by the urinary analyzer was corresponding with the outcome of 10 30/HP erythrocytes(++)determined by the urinary sedimentation microscpy as cited on the item 36 in "Human Mild Trauma Expertise Standard".The urinary sedimentation microscopy could not be substituted by the urinary analyzer examination in the forensic expertise.The result of urinary analyzer examination must be strictly evaluated.
