Simple blood test could uncover hidden diabetes in ER patients
NCT ID NCT04653545
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at over 5,000 adults coming to the emergency room to see how many had undiagnosed type 2 diabetes or pre-diabetes. Researchers used a standard HbA1c blood test, already taken for other reasons, to screen patients. The goal was to find out how common hidden diabetes is in this setting and whether routine screening could help start treatment earlier.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- HbA1c blood test
- What this could lead to
- If successful, this could lead to a simple, routine screening method to catch hidden diabetes early in emergency room patients, potentially improving long-term health outcomes.
- What could go wrong
- This is a completed observational study, not a treatment trial. It only measures how common undiagnosed diabetes is; it does not test a new therapy or prove that screening improves outcomes.
