Description

This test is primarily used to diagnose diabetes in children and adults who are not pregnant. For pregnant women, a different test is recommended. To ensure accurate results, patients need to fast overnight and then consume a 75g glucose solution. A fasting blood sample is taken immediately after. For children, the glucose amount is adjusted to their body weight. Diabetes may be diagnosed if fasting glucose levels are โ‰ฅ126 mg/dL or if glucose levels are โ‰ฅ200 mg/dL two hours after consuming the glucose.

Who should take this test?

This test is suitable for individuals showing symptoms of diabetes or for routine diabetes screening in non-pregnant adults and children.

What type of sample is required?

Three 1 mL plasma samples are needed for this test, collected in fluoride/oxalate (gray-top) tubes.
