It is common for HPV test results to be different twice. It is possible that there was an error in the first test, and there are many reasons for this phenomenon, which may be related to the taking of the material. The second test may also be re-infected, so the patient does not need to worry too much when the results are different twice, but needs to be judged according to the last result. Because the HPV infection may be cleared by the immunity in the body at any time, but it may also be infected at any time. Therefore, if a patient has a high-risk HPV infection, a liquid-based cell test must be done to see if there are precancerous lesions in the cervix.
