Detection of HPV in Norwegian cervical biopsy specimens with type-specific PCR and reverse line blot assays

Abstract

The prevalence of HPV16 increases from grades CIN1 to CIN2 to CIN3. The prevalence of HPV18 did not change significantly with increasing CIN grade. The majority of infections diagnosed as CIN2/3 contained a single HPV type. The type-specific PCR assay had increased detection sensitivity over the reverse line blot assay.
