A colposcopy is a close examination of the cervix and vagina using a colposcope (microscope) to identify any abnormalities.
Women who have had abnormal test results following their cervical smear may need to undergo a colposcopy. This type of procedure can identify any irregularities or changes that have been found during the smear which could possibly – but very rarely – lead to cervical cancer.
Similar to a smear test, you will need to lie back on a special chair and place your legs apart in supports, or ‘stirrups’. A speculum is inserted into the vagina and acetic acid (a vinegar solution) smeared onto your cervix using a swab. The solution turns any abnormal cells white. Iodine is then used to identify the area of abnormal cells, turning any irregularities yellow and staining the normal cells black. The cervix is then closely examined using the colposcope, which is done externally. If any abnormalities are found, a small biopsy (tissue sample) may be taken for testing.
