Diabetics may be required to undergo various different screenings.   A1C tests are different from blood tests you might perform yourself. Taking a blood test tells you what your blood glucose level is at the time. You can think of the A1C test as a summary of how your blood glucose has been over the course of a given period of time. High blood pressure can cause heart problems and strokes, so it is important to check your blood pressure regularly.   A dilated eye exam differs from an eye exam for glasses or contact lenses. An eye doctor uses eye drops to help see the blood vessels deep inside your eyes during a dilated eye exam. These blood vessels are checked by the doctor to see if they have been damaged. A damaged blood vessel inside your eye can seriously impair your vision if not found and treated. The risk of eye problems increases when experiencing high blood pressure and high glucose.   Diabetics may require additional screenings; the best practice is to check with and follow the recommendations of your healthcare provider to manage the condition.
