Why This Test Is Done
Your doctor may order this test if they suspect you have diabetes, prediabetes, or another condition affecting how your body processes blood sugar. It can also help evaluate how well your current treatment plan is working for managing blood sugar levels.
What to Expect Before the Test
You’ll typically fast for a few hours before the test, but your doctor may specify a different fasting period or timing around meals. Bring any medications you’re taking and discuss them with your healthcare provider beforehand.
During the Test
A healthcare professional will draw blood from a vein in your arm. You may feel a slight pinch, but it usually doesn’t cause discomfort. The blood sample will be sent to a lab for analysis.
After the Test
You can usually return to your normal activities immediately. If you had a fasting period, eat a light meal afterward. Check with your doctor if you have any questions about resuming medications or activities.
Reference range
Fasting: 2.6-24.9 μIU/mLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
