To determine the incidence of toluidine blue positive findings after speculum examination of sexual assault victims, we performed a prospective before and after study of 27 female patients presenting after sexual assault to a free-standing nurse examiner clinic. Before the insertion of a speculum, a 1% aqueous solution of toluidine blue was applied to the posterior fourchette and photographs were taken using colposcopy with digital imaging (16 x magnification). After the forensic examination was completed, dye was reapplied. ⋯ Before speculum examination, genital injuries from sexual assault were documented in 67% of the patients (mean number of genital injuries, 1.4). After speculum examination, one patient (3.7%) demonstrated a new genital injury-an abrasion to the labia. Until further studies are performed, use of a speculum should be delayed until after toluidine dye application.
