Continuous Glucose Monitoring-Measured Glucose Levels During Oral Glucose Tolerance Testing in Pregnancy
Main finding · CGM vs BG glucose during OGTTResult — go to the resultDifference 6 ± 13 mg/dLAuthors' conclusion
CGM glucose measurements using Dexcom G6 Pro tended to be slightly higher than BG values during an OGTT, leading to more participants who would have been diagnosed with GDM if the BG-based OGTT thresholds were applied to these CGM-measured glucose values.
Study context
- Population
- Pregnant females undergoing diagnostic oral glucose tolerance test (OGTT) while wearing a blinded continuous glucose monitoring (CGM) sensor
- Participants
- 119 females
- Comparison
- CGM-measured glucose vs blood glucose (BG) during OGTT
- Outcome
- CGM vs BG glucose during OGTT
