Could a simple drink catch hidden diabetes?
NCT ID NCT07233434
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study in Guadeloupe is testing whether an oral glucose tolerance test (OGTT) can find type 2 diabetes in people of African or Indian origin who have normal fasting blood sugar but other risk factors. About 120 adults will take the test and be followed for a year. The goal is to see if this method catches diabetes that standard screening misses.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- oral glucose tolerance test (OGTT)
- What this could lead to
- If successful, this could show that adding an oral glucose test improves early diabetes detection in specific populations, leading to better screening guidelines.
- What could go wrong
- This is a small pilot study (120 people) in one region, so results may not apply broadly. The test is not a treatment and carries no direct benefit to participants.
