Colposcopy is performed after a cervical cytology smear and human papillomavirus screening have been performed. Tissue from the vagina or cervix may need to be taken for biopsy when performing colposcopy, which is an invasive test, so it is usually performed after the first two tests have been performed first. Colposcopy is a medical device used to clinically view cervical, vaginal, and vulvar tissues for changes, and it can be used to assist in locating pathologic biopsies and increase the positive rate of pathologic biopsies. However, screening is often required before tissue from the vagina or cervix can be taken for pathology biopsy, and colposcopy is only required if the screening results are abnormal. The screening tests performed prior to colposcopy are cervical cytology smears and human papillomavirus screening, which are needed for patients with suspicious lesions on cervical cytology smears and positive human papillomavirus screening. If colposcopy is needed, please follow your doctor’s instructions for treatment.
