• You may have water or diet beverages during the test
• No caffeinated beverages during the basal test.

2. No Bolus Insulin Working During the Basal Test

• Do not bolus for at least 4 hours preceding the basal test.
• Do not bolus during the test, unless your blood glucose is above 250**.

3. No Changes in the Body's Normal Glucose Output

• No hypoglycemic episodes for at least 6 hours preceding the basal test.
• No illnesses during the testing (fever, infection, virus)
• No steroid medications being used
• Avoid testing during major stages of menstrual cycle if blood glucose changes are usually noted

4. Allow Basal Insulin to be Delivered Uninterrupted

• Do not put the pump into suspend

5. Maintain low-moderate activity level

• Do not exercise starting 4 hours after last meal/snack.
• You may perform light/moderate exercise soon after last meal/snack if it is your normal time to do so.

6. Monitor blood glucose levels

• Use the same blood glucose meter throughout the testing.
• Check blood glucose level every 2 hours.
• Testing may be performed for 4-12 hours.

** For any readings above 250, stop the basal test and check for ketones. If no ketones, bolus with pump. If ketones are present, give an injection and change infusion set.
