4.4.2.9 Anal Swabs

If rectal penetration is reported or suspected, examine the anal area first.

Examination and evidence collection of the anal area is performed prior to genital because this area can be contaminated when inspecting and collecting vaginal specimens.

Examine the rectal area for injury, and document any noted injuries prior to obtaining swabs.

The use of a minimal amount of water-soluble, non-spermicidal lubricant (water or saline) during the vaginal and/or rectal exam is acceptable and may promote patient comfort.

Remove any foreign bodies, and let them air-dry before placing in the envelope marked ‘Miscellaneous’. Clearly document on the ‘Miscellaneous’ envelope from where the evidence was collected.

Obtain swabs of the rectal area with the cotton-tipped swabs provided in the envelope marked ‘Anal Swabs’.

Indicate on the ‘Anal Swabs’ envelope whether swabs were collected from the outer anal folds or from within the orifice. If both areas were swabbed, package the swabs in separate envelopes, and clearly note on the envelope from where the evidence was collected.

Do one swab at a time. Use the entire surface of each cotton-tipped swab to maximize the amount of sample collected. If particulate matter/fibers are on the swab, do not remove them.

Mark the first swab obtained with a black marker on the distal wooden portion of the swab stick.

Place the four swabs in a stable stand, and let them air-dry. Once dried, place all four swabs back in the pre-labeled ‘Anal Swabs’ envelope.
