Evaluation of a novel microplate colorimetric hybridization genotyping assay for human papillomavirus.

Persistent infection with high-risk human papillomavirus (HR-HPV) has been associated with cervical cancer. Developing assays for the identification of these viral types is of great importance for monitoring patients and controlling strategies. The development of the MCHA (microplate colorimetric hybridization assay), a PCR-based method for identifying six of the most common HR-HPV types (HPV 16, 18, 31, 33, 39 and 45) is described.
