A colposcopy service can be part of a routine gynaecological outpatient department or it may be a specialized unit in a referral centre. In either situation, the facilities for treating cervical precancerous lesions should be made available. A comprehensive colposcopy set up should have a colposcope with ancillary equipment and consumables, cryotherapy equipment with refrigerant gas, and an electrosurgical unit with accessories and a smoke evacuator. A cold coagulator may replace the cryotherapy equipment if a regular supply of refrigerant gas is not feasible.
Colposcopy can also be performed as an outreach service using a portable colposcope. Cervical biopsies and cryotherapy (or, alternatively, thermal ablation) are also feasible in this setup.
