The rape kit procedure may seem like it's prolonging your ordeal, but it is a vital step in reporting and stopping rape--both of which can be powerful tools in your recovery. Even if you are not totally certain that you are going to bring criminal charges, you should take this step. Without it, if you should change your mind later, the rape will be a lot harder to prove and the rapist a lot harder to identify. Because rape is such an intimate crime, the rapist leaves evidence of himself on your body. With all the advances in DNA testing and identification, these microscopic traces of your attacker are your best chance for nailing him.
Rape kit procedure includes photographing any cuts and bruises; taking a saliva sample; combing your pubic hair for any evidence (like his pubic hair); conducting a pelvic exam; checking your underwear for semen stains, which can be used for valuable DNA tests; and cleaning under your fingernails. You will also be asked to relate what happened, and someone, usually a doctor, will write it all down. If the hospital has a rape crisis volunteer or staff member on call, they can be in the room with you during this procedure.
