Who could benefit from this research
✓Could help
Children aged 0–11 who snore, have suspected sleep-disordered breathing, daytime symptoms, or are being evaluated for possible OSA.
✕Less likely to help
Adults, children without symptoms of sleep-disordered breathing, or patients who need a definitive overnight polysomnography for diagnosis may not benefit from this screening test.
What this research studies
If my child snores or has breathing pauses during sleep, this project uses a simple urine sample to look for a set of biomarkers linked to pediatric OSA. PGXL is developing a multiplexed immunoassay that measures several proteins in urine to screen for OSA and potentially monitor treatment response. The company plans to collect samples from children (about 0–11 years) and compare urine results to standard clinical tests like sleep studies. The goal is a CLIA-compatible, easier, and faster screening option than overnight polysomnography.
Why it matters
Potential benefit: Could make screening and monitoring for pediatric OSA quicker, less invasive, and more accessible by using urine samples.
How similar studies have gone: Some biomarker research for OSA exists, but urine-based multiplex immunoassays for pediatric OSA are relatively new and not yet widely validated.
