Wearable sensor may replace the dreaded glucose drink test for gestational diabetes
NCT ID NCT06357728
First seen Aug 10, 2026 · Last updated Aug 11, 2026 · Updated 1 time
Summary
This study tests whether a continuous glucose monitor (CGM) worn on the arm can diagnose gestational diabetes as well as the standard oral glucose tolerance test (OGTT). Pregnant women of Chinese or Indian ethnicity will wear the sensor for up to 10 days and also undergo the OGTT. Researchers will compare glucose readings from both methods and see which better predicts pregnancy outcomes. The goal is to find a more comfortable and informative way to diagnose gestational diabetes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Continuous glucose monitoring (CGM) sensor (Dexcom G6)
- What this could lead to
- If successful, this could lead to a more comfortable and detailed way to diagnose gestational diabetes, potentially replacing the oral glucose tolerance test.
- What could go wrong
- This is a small pilot study, so results may not apply to all populations. The CGM sensor may cause skin irritation, and its accuracy compared to the standard test is still unproven.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Pregnant women of only Chinese or Indian ethnicity 2. Pregnant women between age 21--45 years old 3. Oral glucose tolerance test (OGTT) to be scheduled between 20-35 weeks gestational age 4. OGTT to be done at KK Women's and Children's Hospital Exclusion Criteria: 1. Women with serious skin conditions (e.g. eczema) that precludes wearing the sensor for 10 days 2. Exclusion criteria were pre-existing Type 1 or Type 2 diabetes, mental illness precluding informed consent and women who were diagnosed early (1st or early 2nd trimester for GDM).
