Things for You or Your Health Care Provider to Do at Least Once or Twice a Year to Control Diabetes

A1C test	Have this blood test at least twice a year (See "How can I find out what my average blood glucose is?") Your result will tell you what your average blood glucose level was for the past 2 to 3 months.
Blood lipid (fats) lab tests	Get a blood test to check your total cholesterol—aim for under 200 LDL—aim for under 100 HDL—men: aim for above 40; women: aim for above 50 triglycerides—aim for under 150 These test results will help you plan how to prevent heart attack and stroke.
Kidney function tests	Ask for tests to check your urine for protein. The results will tell you how well your kidneys are working.
Dilated eye exam	See your eye doctor once a year for a complete eye exam.
Dental exam	See your dentist twice a year for a cleaning and checkup.
Flu shot	Get a flu shot each year.
Foot exam	Ask your health care provider to check your feet to make sure your foot nerves and your blood circulation are OK.
