When to get this test
Diabetes diagnosis
Helps confirm diabetes or prediabetes when fasting or random sugar results are borderline.
Glucose handling
Shows how efficiently your body clears sugar from the blood after a measured glucose load.
Risk assessment
Useful for people with risk factors who need a clearer picture than a single sugar reading.
How to prepare
01
Fast for 8–12 hours before the blood draw; water is allowed.
02
You will drink a 75 g glucose solution, then stay at the clinic for timed blood draws over the next couple of hours.
03
Stay seated and avoid eating, smoking, or heavy activity between draws.
Common questions
How long does the OGTT take?
Plan for about two hours, since blood is drawn at set time points after you finish the glucose drink.
Can I leave between blood draws?
Please stay at the clinic and remain seated, as the timing of each draw is important for accurate results.
What if the glucose drink makes me feel unwell?
Mild nausea can happen. Let our staff know right away if you feel faint or unwell during the test.
