TCT is only one kind of cervical cancer screening test, if the diagnosis is to be confirmed, it needs to be combined with HPV test results and, if necessary, colposcopy, and if positive signs are found through colposcopy, pathological examination is needed. TCT is only a screening test, which has a great reference value and may have a small error, but a combination of HPV test, colposcopy and pathology is the final diagnosis.
