There are 3 different ways to test for diabetes.
1) Check blood glucose after an overnight fast. As long as the Gatorade was not consumed after the fast has started, it should not have impacted the result.
2) Check your hemoglobin A1c. This blood test reflects the estimated average blood glucose over the past 3 months. An abnormal A1c level tells us that his entire diet and lifestyle should be evaluated including the regular consumption of sweetened beverages.
3) Do an Oral Glucose Tolerance Test (OGTT) - Drink a particular amount of sugar drink after an overnight fast and test for blood glucose response in 2 hours. This test is not performed regularly.
The good news is that through lifestyle changes, many individuals with pre-diabetes can revert back to normal. Please talk to your health care providers about how to do this.
