People at risk of diabetes should have their blood sugar measured, Buse added. "If the fasting glucose test is elevated more than 100 milligrams per deciliter [of blood], it means that you are at risk of developing diabetes and you may have some excess risk of heart disease, particularly if you are a woman," he said.
The ADA recommends that everyone over age 45 should have a fasting glucose test, Buse said. "Normal is less than 100 milligrams per deciliter, so 99 is normal, 100 isn't," he said. "If the test is normal it should be repeated every three years."
People under 45 who are overweight and have any risk factors for diabetes should be screened earlier and more often, he said.
