A fasting glucose level below 40 mg/dL (2.2 mmol/L) in women or below 50 mg/dL (2.8 mmol/L) in men that is accompanied by symptoms of hypoglycemia may mean you have an insulinoma, a tumor that produces abnormally high amounts of insulin.
Taking a medicine. Make sure that your doctor knows about any medicines you take and how often you take them.
What To Think About
Glucose levels in urine can also be measured. Many people with diabetes have glucose in their urine. But the level in the blood must be very high before glucose can be detected in the urine. For this reason, tests for glucose in urine are not used to diagnose or monitor diabetes. To learn more, see Urine Test.
If you have diabetes, you will be able to measure your blood glucose levels at home. To learn more, see Home Blood Glucose Test.
