Repeat Late GDM Testing and Cesarean Delivery Rates
144 participantsStarted 2026-08-01
Plain-language summary
The goal of this randomized trial is determine if re-testing for gestational diabetes in the third trimester after an ultrasound measurement of estimated fetal weight (EFW) or abdominal circumference greater than 90%ile decreases cesarean delivery rate, and to evaluate the optimal method of re-testing. The main question it aims to answer is:
Does repeat testing for gestational diabetes and management of hyperglycemia decrease the cesarean delivery rate in fetuses measuring \>90%ile by estimated fetal weight (EFW) or abdominal circumference (AC) on ultrasound in the third trimester.
Participants will be randomized into two groups: Group 1 will undergo a repeat glucose tolerance test (GTT) with blinded continuous glucose monitor (CGM) and group 2 will have no intervention. Participants in group 1 will receive nutrition counseling as this would be standard in patients at high risk for gestational diabetes.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
