A 31-year-old woman who had gestational diabetes mellitus delivers at term. For postpartum assessment of her glucose status, the recommended investigation is:

• A Fasting plasma glucose alone at six weeks
• B 75 g oral glucose tolerance test at six weeks postpartum ✓
• C HbA1c at twelve weeks
• D Random plasma glucose at discharge

Explanation

All women with gestational diabetes should undergo a 75 g OGTT between four and twelve weeks postpartum, classically at six weeks, to detect overt diabetes or impaired glucose tolerance. Fasting glucose alone misses isolated post-load hyperglycaemia, and random glucose at discharge is unreliable because of ongoing metabolic change. HbA1c is affected by postpartum haematological shifts and is not the standard confirmatory test at this visit.
