Hypothesis
What maternal characteristics are associated with false positive HIV EIA testing at delivery?
Conclusion
False positive HIV testing at delivery using EIA is associated with young maternal age and nulliparity in this population.
Supporting Evidence
- 99% of patients tested negative for HIV.
- 0.3% of patients had false positive results.
- Young and nulliparous women were more likely to have false positive results.
Takeaway
The study found that younger women who have never given birth are more likely to get a false positive result on HIV tests during delivery.
Methodology
A review of pregnant women who delivered at Parkland Hospital between 2005 and 2008, analyzing HIV EIA test results and maternal characteristics.
Potential Biases
The study cannot identify causal relationships or explain why the associations exist.
Limitations
The study was conducted at a single institution with a predominantly Hispanic population, limiting generalizability.
Participant Demographics
Predominantly Hispanic women who delivered at Parkland Hospital.
