Colposcopy with digital photography is used in the evaluation of suspected sexual assault victims. Its main advantage over naked-eye examination alone is:
- A It allows real-time blood typing from vaginal secretions
- B It can detect hymenal injury in all sexual assault victims
- C It provides magnification and photographic documentation of subtle mucosal injuries that may be invisible to the naked eye, creating a permanent record ✓
- D It identifies the perpetrator through DNA analysis of any deposited material
Correct answer: C. It provides magnification and photographic documentation of subtle mucosal injuries that may be invisible to the naked eye, creating a permanent record
Explanation
Colposcopy provides illuminated magnification (6–15×) of the genital/anal anatomy, allowing the examiner to detect subtle mucosal abrasions, petechiae, micro-lacerations, and vascular injury patterns not visible to the naked eye. Digital photodocumentation creates a medico-legal record for court use and allows peer review. It does not perform blood typing, DNA analysis, or guarantee detection of injury (many sexual assaults leave no detectable mucosal injury). The absence of colposcopic findings does not exclude penetration.
