Vaginal swab vs. urine: Which is more accurate for detection of chlamydia, GC, and trich?

Evidence from this meta-analysis supports the CDC's recommendation that vaginal swabs are the optimal sample type for women being tested for chlamydia (CT), gonorrhea (NG), and/or trichomoniasis (TV)—despite the fact that urine specimens are often used. Pooled sensitivity estimates for vaginal swabs and urine, respectively, were 94.1% and 86.9% for CT, 96.5% and 90.7% for NG, and 98.0% and 95.1% for TV.
