Abstract. Hybrid Capture 2 (hc2), a clinical test for carcinogenic human papillomavirus (HPV) DNA, has proven to be a sensitive but only modestly specific predictor of cervical precancer and cancer risk. Some of its nonspecificity for clinical end points can be ascribed to cross-reactivity with noncarcinogenic HPV genotypes.
See related article by Dijkstra et al., p. 55The POBASCAM trial (1) was one of the earliest and longest randomized controlled trials to address the test performance of high-risk HPV (hrHPV) testing to detect cervical precancerous lesions. It builds on the evidence presented in HART (2). Of importance is the 29-year-old starting age for study enrollment. The European cohort study (3) included
Additionally, the Inv2 assay, which offers high-throughput, semiautomated DNA extraction, allows the subgrouping of HPV types by differential probe sets, could provide a useful test for screening for HPV, and has the potential to provide an improved means of risk stratification and the selection of patients for further HPV subtyping.
This test detects high-risk HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) and differentiates HPV 16 and 18 associated with cervical cancer and its precursor lesions. Sensitivity may be affected by specimen collection methods, stage of infection, and the presence of interfering substances.

While HPV can remain dormant in the body for a long time, studies show that most people clear the virus within one to two years [3]. Just look at one study’s findings on HPV infection clearance time in college-aged women [4]: 70% of women cleared their HPV infection within one year. 91% of women cleared their HPV infection within two years.
Acceptable test for routine cervical cancer screening at 3-year intervals in individuals 25-65 years of age with a cervix. Preferred test is Human Papillomavirus (HPV), High Risk with 16 and 18 Genotype by Nucleic Acid Amplification (NAA), ThinPrep (3003005). ||Transport cervical specimen in the original collection kit.
Use. High-risk HPV test is used for types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68, without differentiation of the individual type. If the initial high-risk test is positive, then the residual specimen will be tested for HPV types 16 and 18,45; type 18 cannot be differentiated from type 45.

A strategy of primary HPV DNA testing with a second triage test at a 5-yearly interval for women living with HIV was more effective at reducing cervical cancer cases and deaths than screening with visual inspection with acetic acid (VIA) every 3 years. The inclusion of a second triage test among women living with HIV who screen HPV-positive
