WEDNESDAY, Aug. 27, 2025 (HealthDay News) — Detecting diabetes might soon be as easy as breathing into a device, a new study says.

An experimental breath test sorted out type 2 diabetes patients from healthy people, based on their exhalations, researchers report in the September issue of the Chemical Engineering Journal .

“This sensor only requires that you exhale into a bag, dip the sensor in and wait a few minutes for results,” senior researcher Huanyu “Larry” Cheng , an associate professor of engineering science and mechanics at Penn State, said in a news release.

If validated, this test could prove simpler
