Colposcopy procedure steps: a clinic workflow with the equipment behind it

Step 1: preparing the room and equipment

Before the session the team checks that the colposcope powers up, the light output is steady, the focus and filter move freely, and the stand locks. The couch with leg supports is positioned, the stool is at the right height, and the instrument tray, solutions, swabs, biopsy forceps, specimen containers and labels are laid out in reach.

A good general examination light helps the whole room. The Sim.LED 3500+ is offered as ceiling, wall or mobile unit with 90,000 lx central illuminance at 1 m, Ra 96 and a sealed, Anti.BAC-coated body, which suits a room that is wiped down between patients. A separate colposcope still provides the magnified view.

Finally, confirm that the documentation route works before the first patient: camera or image storage, the request form for the laboratory, and a way to record which instrument set was used.

Step 2: positioning and speculum insertion

The patient is positioned on the couch and the clinician inserts a speculum chosen for the examination. Instrument tray planning matters here: several sizes should be available so that the clinician does not interrupt the examination to look for another one.

The REDA range includes Cusco, Pederson, Collin and Sims vaginal specula, as well as a tenaculum and biopsy punch forceps, within its gynaecology instruments. Reusable specula go through the standard decontamination cycle after each patient; single-use specula are an alternative the clinic may choose.

Step 3: magnified examination, acetic acid and iodine

With the colposcope positioned at the working distance, the clinician first inspects the cervix, then applies the solutions used in the clinic's protocol, such as saline, acetic acid and an iodine solution, and observes the response under magnification. A green filter is often used to look at vascular patterns.

This stage explains how colposcopy works as a technology: it is an optical viewing system and does not itself treat anything. Equipment questions are about stability of the stand, quality of illumination, filters, and whether a camera is fitted. Solutions and swabs are consumables that should be stocked and dated.

Step 4: colposcopy biopsy and haemostasis

If the clinician decides a sample is needed, a colposcopy biopsy is taken from the chosen area with biopsy punch forceps, with an endocervical curette in some protocols. The specimen is placed in a labelled container with fixative and the site is managed with the haemostatic agent specified in the clinic's protocol.

Clinics that also perform loop excision require an electrosurgical generator, loop electrodes, a smoke evacuation route and a return electrode. The BOWA ARC 350 offers two monopolar and two bipolar outputs up to 400 W with procedure presets and neutral-electrode monitoring; see our LEEP equipment guide for the set-up.

• Biopsy punch forceps, tenaculum if used, endocervical sampling instrument.
• Specimen containers, fixative, labels and a laboratory request route.
• Haemostatic agents and swabs per protocol.
• Electrosurgical generator and electrodes only if excision is offered.

Step 5: documentation, reprocessing and turnover

The clinician records findings, with images if the colposcope has a camera, and the nurse labels and dispatches samples. Reusable instruments are cleaned, inspected, packed and sterilized; the stand and couch are wiped with the approved disinfectant. The duration of a session depends on the protocol, whether sampling is needed and room turnover, so clinics should measure their own times when planning appointment slots rather than rely on a generic figure.
