Answer: (A)

After a rape, STI testing should be sequenced to maximize detection and account for window periods. Start with nucleic acid amplification testing for chlamydia and gonorrhea using an appropriate vaginal/urethral specimen. These infections are common and NAATs are highly sensitive, providing rapid, actionable results that guide immediate treatment decisions. Next, evaluate for trichomoniasis with a wet mount, culture, or a point-of-care test on a vaginal swab. This step adds detection of another common infection with distinct treatment implications, and doing it after the initial NAATs helps ensure comprehensive screening while using available specimens efficiently. Then obtain a serum sample for HIV, hepatitis B, and syphilis to establish baseline serostatus. Serologic infections may have window periods, so baseline testing is crucial for counseling and planning follow-up care and surveillance. Finally, repeat serologic tests for HIV and syphilis at follow-up to detect infections that may seroconvert after the initial test. This accounts for the diagnostic window periods and helps ensure any late seroconversion is identified.
