What this test is
The glucose blood test is a laboratory test that measures the concentration of glucose (sugar) in a blood sample. Glucose is the primary fuel for your body's cells and is especially important for brain function. This test can be done after fasting, randomly, or as part of a timed series.
What it measures

What the test involves
A healthcare professional collects a small sample of blood, usually from a vein in your arm, using a needle. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order a glucose blood test to screen for diabetes or prediabetes, or to monitor blood sugar levels in someone already diagnosed with a sugar-related condition. It can also be used to investigate symptoms such as fatigue, excessive thirst, or frequent urination.
