If your healthcare provider believes you may have prediabetes, you will need certain exams and tests. You should also expect to be asked questions about your health history, your symptoms, risk factors and family history of disease. Understanding your background will help your provider make a diagnosis.
He or she may also give you a physical exam that includes bloodwork.
An A1C test is a blood test measures your average blood glucose over the last three months.
A fasting plasma glucose test is a blood test measures your current blood glucose level when you have not had anything to eat or drink for eight hours.
