A negative (nonreactive) RPR is compatible with a person not having syphilis, but in the early stages of the disease, the RPR often gives false negative results. Conversely, a false positive RPR can be encountered in infectiousmononucleosis,lupus, antiphospholipid antibody syndrome,hepatitisA,leprosy...
All 91 RPR-nonreactive serum samples were negative for HIV antibody. Of the 160 RPR-reactive serum samples, 26 were initially reactive and 11 were repeatedly reactive for HIV antibody. Of these 26, only six (all repeatedly reactive) were positive by indirect fluorescent antibody and Western ...

快速血浆反应素环状卡片试验(RPR)是80年代问世的非特异性梅毒血清学试验,所用抗原为标准的牛心肌脂抗原,该方法操作简便、迅速,适用于大量标本检测,目前许多血站用RPR试验对献血者进行梅毒普查。RPR试验和DF方法对一期梅毒的诊断相互配合,可早期诊断梅毒。缺点是当抗体含量过高时,易出现假阴性反应,即前带现象(prozone p...
Negative test:Absence of antigen-antibody clumps. Indicated by slight roughness and no aggregates. All reactive serum requiresserial dilutionto estimate antibody titer. The titre is reported as the reciprocal of the highest dilution, which shows a positive test result. ...
