A new breath test detects serious bacterial infections in 10 minutes using harmless labeled sugars and portable tech, showing promise for faster, more accurate diagnosis and treatment monitoring.
A new breath test can detect serious bacterial infections in as little as 10 minutes using carbon-13-labeled sugars and sugar alcohols that bacteria metabolize into detectable carbon dioxide, which appears in the breath.
In animal studies, the test successfully identified infections like pneumonia, sepsis, and bone or muscle infections, with infected mice showing rapid increases in labeled gas while healthy ones did not.
The method, inspired by a test for H. pylori, uses safe compounds and portable equipment, enabling quick diagnosis and real-time monitoring of antibiotic treatment.
Researchers say it could improve care in urgent settings, reduce antibiotic overuse, and help combat resistance.
The test has not yet been tested in humans.
