Question

A 30-year-old G2P1 woman at 26 weeks' gestation attends routine antenatal care. She has no history of diabetes, BMI is 27 kg/m² and previous pregnancy was uncomplicated. According to Canadian guidelines, what is the recommended screening approach for gestational diabetes in this low-risk woman?

Accepted Answer

Screen with a 50 g glucose challenge test and, if abnormal, perform a 75 g oral glucose tolerance test.

Answer

No screening is required because she is low risk and under 35 years old.

Answer

Perform a 75 g oral glucose tolerance test without prior screening.

Answer

Screen only if random plasma glucose exceeds 11.1 mmol/L later in pregnancy.

Answer

Use HbA1c alone as the screening test at 26 weeks.
