Could a breath test replace blood draws for metabolic disease monitoring?

NCT ID NCT07704606

First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time

Summary

This study measures specific substances (metabolites) in the breath and blood of people with inherited metabolic disorders, those on a special ketogenic diet for epilepsy, and healthy volunteers. The goal is to see if a simple breath test can reliably track these metabolites, potentially replacing painful and frequent blood tests. Researchers will also test a handheld breath sensor for possible home monitoring.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this could lead to a painless, breath-based method for monitoring certain metabolic conditions, reducing the need for frequent blood draws.
What could go wrong
This is an early observational study, not a treatment trial. The breath sensor may not be accurate enough to replace blood tests, and results may not apply to all patients.
