摘　　要：目的通过参加美国病理家学会(CAP)组织的血液寄生虫检查能力验证(PT)来评估我室能力,为进一步提高血液寄生虫检查的质量奠定基础。方法将CAP发放的厚膜血片和薄膜血片于10个工作日内按常规血液寄生虫检查方法进行检查并通过网络将结果直接提交给CAP。结果15份标本中有13份结果正确,正确率为87%。没有假阴性和假阳性结果。我室对微丝蚴和四种疟原虫(包括3份低虫血症标本)的识别能力较强(100%正确),由于缺乏经验,本室将冈比锥虫误报成枯氏锥虫,将巴贝氏虫误认成利什曼原虫。结论通过参加CAP能力验证将我室的血液寄生虫检查标准化,掌握了易被误认成恶性疟原虫的巴贝氏虫的鉴别要点并提高了实验室全体成员识别寄生虫的能力。Objective To evaluate the performance of blood parasites identification in our lab through CAP Blood Parasites Survey and provide the basis for improving experimental quality. Methods The samples from CAP were examined within 10 working days in the same way as clinical specimens. Then, all the results were feedback to CAP by internet, Results The corrective rate was 87% （13/15）. There were no false negative and false positive results. Our lab had good performance （100%） in identifying microfilaria and four kinds of plasmodium （including 3 samples with low parasitemia）. Due to lack of experience, we misidentified Tryp. GambiBabesia spp. and improved the ability to identify blood parasites.
