Hypothesis
What are the optimal methods for collecting samples from the female genital tract to measure immune mediators?
Conclusion
Endocervical swabs and cervicovaginal lavage collected with saline provide the best recovery of immune mediators.
Supporting Evidence
- Endocervical swabs recovered the highest levels of immune mediators compared to vaginal swabs.
- Cervicovaginal lavage with saline provided the best recovery of antimicrobial activity.
- Bacterial vaginosis affected the recovery of certain immune mediators.
- Swab type did not significantly influence recovery after correcting for protein content.
Takeaway
This study looked at how to best collect samples from women's genital areas to measure immune responses, finding that certain methods work better than others.
Methodology
Samples were collected from 48 women using various swabs and cervicovaginal lavage with different diluents, and immune mediators were measured using Luminex or ELISA.
Potential Biases
Potential bias in participant selection and the influence of bacterial vaginosis on results.
Limitations
The study may not account for all variables affecting immune mediator recovery, and the sample size is limited to one geographic area.
Participant Demographics
Mean age was 30.8 years; 46% African-American, 40% white, 12% Asian, 2% other; 50% had bacterial vaginosis.
