Comparison of anal and rectal swabs in the diagnosis of anorectal gonorrhoea in women.

Abstract

Among 228 women with gonorrhea (confirmed by culture), swabs taken blindly from the anal canal gave positive results in 26.3% and those taken from the rectum under direct vision in 27.6%. Swabs from both sites gave positive results in 23.2% of patients, from the anal canal alone in 3.1% and from the rectum alone in 4.4%. Culture of anal canal swabs seems to give as reliable results as rectal swabs when proctoscopy cannot be carried out.
