Introduction
TCT and HPV tests can usually be performed using the same sample, as both are conducted by collecting exfoliated cervical cells. During combined screening, both tests can be carried out simultaneously during a single gynecological examination, without the need for separate procedures. Whether undergoing TCT, HPV testing, or both, the process should be guided by a physician to ensure the accuracy of test results and the appropriateness of any follow-up management.
Under normal circumstances, TCT and HPV tests can usually be performed simultaneously, as both involve collecting cervical exfoliated cells. During combined screening, both tests can be conducted during a single gynecological examination, eliminating the need for separate procedures. Detailed analysis is as follows:
The specific procedure involves the doctor first inserting a speculum to expose the cervix. Then, a specialized sampling brush is used to collect exfoliated cells from the cervical canal and the cervix's surface. These samples are then placed separately into a TCT preservation solution for cytological analysis and into an HPV test tube for viral nucleic acid detection. The entire sampling process takes only a few minutes and causes minimal discomfort to the patient.
This combined sampling method improves the efficiency of cervical cancer screening by simultaneously capturing information on both cellular morphological abnormalities and viral infection. It is currently the recommended screening protocol, especially suitable for women over 30 years old. It should be noted that sampling should be done outside of the menstrual period, and sexual intercourse, vaginal douching, or medication should be avoided 48 hours before the examination to ensure sample quality.
Whether undergoing TCT or HPV testing, or both together, the procedures should always be performed under a doctor's guidance to ensure the accuracy of test results and the appropriateness of subsequent management. Additionally, maintaining healthy lifestyle habits and undergoing regular physical examinations contribute to women's health.
