What does my result mean?

What this test checks

The test measures glucose in the blood 2 hours after a normal meal. It is useful for people with a family history of diabetes, extra weight, or fasting sugar near the upper limit, and for people with diabetes to see how meals and medicines affect them. How often to test depends on your doctor. The cut-offs below come from the standard 2-hour glucose test and are widely used for PP reports.

Common reasons for a high value

• Prediabetes or diabetes
• A very heavy or sugary meal before the test
• Giving the sample earlier than 2 hours after eating
• Stress, infection or a recent illness
• Some medicines, such as steroids

Common reasons for a low value

• Giving the sample much later than 2 hours after the meal
• A very small or low-carbohydrate meal
• Diabetes medicines or insulin, especially with a light meal
• Heavy exercise after the meal

How to prepare

Eat your normal meal and note the time you start. Give the sample exactly 2 hours after starting the meal, without eating anything more in between (plain water is fine). Take regular medicines as your doctor has advised.
