Could a home sugar test replace the clinic visit for diabetes diagnosis?
NCT ID NCT06862128
First seen Jun 27, 2026 · Last updated Aug 06, 2026 · Updated 2 times
Summary
This study compares a self-administered oral glucose tolerance test (OGTT) at home using a continuous glucose monitor (CGM) with the standard clinic-based OGTT. 75 adults with prediabetes will undergo both tests to see if the home version accurately diagnoses blood sugar problems. The goal is to make testing more convenient and accessible.
