The HPV test is a pathological analysis of fluid cells from the cervical canal, which is generally accurate at about 85%-90%. It is recommended that the test be done together with TCT, which can help increase the accuracy by 97%-98%. The cost of the HPV test alone is around 400 RMB and the cost of TCT is around 300 RMB, which adds up to around 800 RMB. There are certain conditions for TCT and HPV tests, such as no intercourse within three days, no vaginal washing within three days, and no vaginal examination within three days to avoid errors in the results.
