Gestational diabetes glucose test

Glucose screening and diagnostic testing are not interchangeable, and fasting, drink, timing and thresholds vary by protocol.

Direct guidance

What to know or do

Follow the exact instructions from the testing service, tell them if you vomit or cannot complete the drink and ask how and when results will be communicated. Do not change diet just to influence the test unless instructed.

What changes the answer

  • Whether this is screening, diagnosis, monitoring, treatment or birth planning
  • Pregnancy week, previous results and what the result could change
  • Benefits, limits, alternatives, follow-up and the time available to decide

When to get individual help

Check the exact item or situation with a doctor, midwife, pharmacist or relevant clinician; the name of a broad category is not enough for a personal decision.
