改良PSA检测法在精斑检验中的应用

摘要

Objective To improve the positive detection rate and reduce the the false negative detection rate by comparing the conventional PSA method with the improved PSA method. Method Using a conventional PSA method and improved PSA method to inspection of samples for the test preparation,comparing the positive detection rate between the conventional and the improved PSA method. Do the statistical analysis. Results The improved PSA test method has a higher positive detection rate, the difference was statistically significant (P< 0.05 ). Conclu-Sions The improved PSA method can reduce the possibility of a false negative result and improbe the PSA test positive detection rate in the practical forensic cases%目的 对两种PSA检测法进行实验研究,以期提高PSA检测法的阳性检出率,减少假阴性结果的产生.方法 用常规PSA法及改良PSA法分别对备检检材进行检验,比较两种方法的阳性检出率,并进行统计学分析.结果 改良PSA检测方法具有较高的阳性检出率,差异有统计学意义(P＜0.05).结论 改良PSA检测法在实际检案中减少了案件样本漏检数,提高了PSA检测的阳性检出率.
