We compared Hybrid Capture, a new technique for detection of human papillomaviruses (HPV), with a PCR assay based on L1 consensus primers. By both methods, the HPV prevalence was higher in human immunodeficiency virus (HIV)-positive women than in HIV-negative women. PCR had a higher sensitivity (0.89 versus 0.48) but lower specificity (0.43 versus 0.93) for detection of Pap smear abnormalities, compared to Hybrid Capture. The higher intensity of hybridization signal by PCR was related to higher estimates of viral load by Hybrid Capture.
我们将一种用于检测人乳头瘤病毒(HPV)的新技术——杂交捕获法,与基于L1共有引物的聚合酶链反应(PCR)检测法进行了比较。通过这两种方法均发现,人类免疫缺陷病毒(HIV)阳性女性中的HPV感染率高于HIV阴性女性。与杂交捕获法相比,PCR检测巴氏涂片异常的灵敏度更高(分别为0.89和0.48),但特异性更低(分别为0.43和0.93)。PCR杂交信号强度更高与杂交捕获法对病毒载量的更高估计值相关。
