Methods for detection of HPV infection and its clinical utility

HPVs cannot be cultured and the detection of virus relies on a variety of techniques used in immunology, serology, and molecular biology. Currently the only FDA-approved commercially available method for the detection of HPV DNA is the Hybrid Capture assay, version hc2 (Digene, Gaithersburg, MD, USA) which is able to detect 13 high-risk types of HPV. The advantage of PCR-based methods of HPV DNA detection is that they allow for the identification of different types of HPV. This article discusses the advantages and disadvantages of the different methods of HPV DNA detection. HPV DNA testing can be used in a variety of clinical scenarios that include a primary screening test, particularly in women older than 30 years; as an adjunctive test to cytology; to triage women who have an equivocal cytologic finding, e.g., ASC-US, or for follow up post-treatment. In addition, HPV DNA testing can be performed on samples obtained by women themselves (so-called self-sampling), which may be useful in women who are resistant to undergoing gynecologic examinations.
