What is the significance of HPV DNA typing?

HPV DNA typing tests are usually performed at the same time as cervical TCT cytology. HPV DNA typing tests are used to identify HPV DNA infection and to classify virus types. HPV infection is divided into low-risk and high-risk types. Low-risk HPV infection generally does not cause cervical cancer or precancerous lesions, but persistent infection with high-risk HPV viruses can directly cause cervical cancer and precancerous lesions, such as CIN2-3, i.e., squamous cell squamous cell moderate to severe dysplasia can develop into cervical cancer. HPV-DNA typing is of great significance to patients.
