title: Comparison of the Cobas 4800 HPV test and the Seeplex HPV4A ACE with the hybrid capture 2 test.
abstract: BACKGROUND
  It is well-known that persistent cervical infections with high-risk human papillomavirus (HPV) are related to the development of high-grade cervical intraepithelial neoplasia and invasive cervical cancer and that infection with HPV 16 and HPV 18 accounts for approximately 70% of all cases of invasive cervical cancer.
  
  
  METHODS
  We performed 3 HPV molecular tests-the Cobas 4800 HPV test, the Seeplex HPV4A ACE, and the hybrid capture 2 (HC2) test-in 146 cervical swab samples to compare between these three tests.
  
  
  RESULTS
  There was a concordance rate of 82.8% between the results of the Cobas 4800 HPV and the HC2 test and a concordance rate of 84.9% between the results of the Seeplex HPV4A ACE and the HC2 test. Between the Cobas 4800 HPV test and the Seeplex HPV4A ACE, there was a concordance rate of 89.6% in the detection of high-risk HPV between the results and a concordance rate of 98.7% in the detection of HPV 16 or 18. When an abnormal Pap test was defined as ≥ low grade squamous intraepithelial lesion (LSIL), the sensitivity of the Cobas 4800 HPV test, the Seeplex HPV4A ACE and the HC2 test were 71.1%, 80.0%, and 88.9%, respectively, while their specificities were 76.4%, 74.5%, and 67.9%, respectively.
  
  
  CONCLUSIONS
  The results of this study suggest that the Cobas 4800 HPV test and the Seeplex HPV4A ACE may be as effective as the HC2 test in detecting HR HPV and that the concordance between the results of the Cobas 4800 HPV test and the Seeplex HDV4A ACE may be higher in the detection of HPV 16 and HPV18 than concerning high-risk HPV.
