New breath test may spot jaundice risk in newborns without needles
NCT ID NCT07346976
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing a device that measures carbon monoxide in a newborn's breath to help diagnose jaundice. Jaundice is common in newborns and can be serious if not treated. The device is non-invasive and could replace or reduce the need for blood tests. Researchers will measure breath carbon monoxide levels in 100 healthy full-term infants over their first three days of life to find the best cutoff values for predicting jaundice risk.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Erythrocyte Life Span Tester (device measuring end-tidal carbon monoxide)
What this could lead to
If successful, this could provide a simple, non-invasive breath test to help doctors diagnose and manage newborn jaundice more accurately.
What could go wrong
This is an early observational study with only 100 infants, so results may not apply to all newborns. The device's reliability and practical benefit are still unproven.
