OBJECTIVES
The Xpert HPV Assay (Xpert; Cepheid, Sunnyvale, CA) was developed for the multianalytic GeneXpert platform.
METHODS
In a colposcopy referral population of 708 women living in the United States, two cervical specimens, A and B, were collected, and both were tested by the Xpert assay for high-risk human papillomavirus (hrHPV) DNA, permitting an evaluation of its test reliability. Specimen B was also tested by Hybrid Capture 2 (hc2; Qiagen, Germantown, MD) and the cobas HPV Test (cobas; Roche Molecular Systems, Pleasanton, CA).
RESULTS
The κ and percent agreement for any hrHPV for the two Xpert results were 0.88 and 94.5%, respectively. There was no statistical difference in testing positive on both specimens by Xpert (P = .62). The sensitivity for detection of cervical intraepithelial neoplasia grade 2 or more severe (CIN2+) was 89.0% using specimen A and 90.4% using specimen B for Xpert, 90.4% for cobas, and 81.6% for hc2.
CONCLUSIONS
The Xpert assay was sensitive and reliable for the detection of hrHPV and the identification of women with CIN2+.
目的
Xpert HPV检测法（Xpert；赛沛公司，加利福尼亚州桑尼维尔市）是为多分析物GeneXpert平台开发的。
方法
在美国的708名接受阴道镜检查转诊的女性人群中，采集了两份宫颈标本A和B，并都通过Xpert检测法检测高危型人乳头瘤病毒（hrHPV）DNA，从而评估其检测可靠性。标本B还通过杂交捕获2代检测法（hc2；凯杰公司，马里兰州日耳曼敦市）和cobas HPV检测法（cobas；罗氏分子系统公司，加利福尼亚州普莱森顿市）进行检测。
结果
两次Xpert检测结果中任何hrHPV的κ值和一致性百分比分别为0.88和94.5%。Xpert检测两份标本均呈阳性的情况无统计学差异（P = 0.62）。对于检测宫颈上皮内瘤变2级或更严重病变（CIN2+），使用标本A时Xpert检测法的灵敏度为89.0%，使用标本B时为90.4%，cobas检测法为90.4%，hc2检测法为81.6%。
结论
Xpert检测法在检测hrHPV以及识别CIN2+女性方面灵敏且可靠。
