Dr. Lamont Tyler currently serves as the medical director of specialty physician services at OSF St. Joseph Medical Center. Alongside his career, Dr. Lamont Tyler supports the American Diabetes Association, which offers information about topics such as testing for diabetes. If a patient has high blood glucose levels, he or she has a risk of developing diabetes. A doctor can diagnose prediabetes by measuring blood sugar, but a second test provides greater accuracy in diagnosis. Three common types of tests used for diagnosis are the A1C, FPG, and OFTT: The A1C test can measure the patient's average blood glucose from the past two to three months. With this test, a normal blood sugar range lies under 5.7 percent, a prediabetic level is between 5.7 and 6.4 percent, and a diabetic level is at 6.5 percent or higher. The Fasting Plasma Glucose (FPG) test requires the patient to fast (not eat or drink anything except water) for a minimum of 8 hours prior to taking the test. Normal results from this test include anything under 100 milligrams per deciliter (mg/dl), while a prediabetic result falls between 100 and 125 mg/dl and a diabetic result is over 125 mg/dl. The Oral Glucose Test (OFTT) measures a patient's blood sugar over two hours. The OFTT determines the blood glucose level at the beginning of the session and then two hours after the patient drinks something sweet. The OFTT aims to determine how the body processes glucose. A normal result is less than 140 mg/dl at the end of the two hours, while a prediabetic result falls between 140 and 199 mg/dl and a diabetic result is 200 mg/dl or more.
