The parent and child will be asked if they want to use a meter to test the child's hemoglobin A1c at home. If they want to do this, they will be given the meter and asked to test the child's A1c two times on the day before one of the visits. The two tests will be done at the same time and they will also be asked to check the child's blood sugar at the same time. The test involves a fingerstick similar to testing the blood sugar level with a home glucose meter.
