Human papilloma virus (HPV) can cause cervical cancer.  9-valent vaccine can neutralize 90% of cancer-causing subtypes, but cannot protect women who have already been infected with HPV.

Chen Yiyou, Chief Scientist of Nuohui Health Research Center in Zhejiang, has designed a new test for HPV in urine. With this test, detection of the currently recognized high-risk viruses are possible. Sensitivity of HPV type16 and type18 are very high, and sensitivity of detection of precancerous lesions reaches 96.8%.
