Detection of high-risk HPV viruses

The detection of high-risk HPV viruses is crucial for the prevention and early detection of cervical cancer. In this study, researchers evaluated the value of a sample genotyping system compared with the traditional real-time PCR method. They randomly selected 365 samples (representing 7,259 women) after running them through real-time PCR, which they then analyzed using the fully automated GenPlex® system. This system identifies 24 HPV virus types using a combination of PCR and microarray-based reverse hybridization. From the real-time PCR, 76 were negative for high-risk HPV, and 289 were positive. The GenPlex® system identified a larger number of positive cases, 73 with a type of HPV not covered by real-time PCR, and 20 potentially due to a DNA concentration undetectable by PCR.
