Self Monitoring of Blood Glucose (SMBG)
Self monitoring of blood glucose is an opportunity for people with diabetes to take control of their health. The main goal of treatment is to keep blood glucose levels in the normal or near-normal range. Monitoring blood glucose levels is one of the best ways of determining how well a diabetes treatment plan is working.

Self monitoring of blood glucose allows a person to know their blood glucose level at any time and helps to prevent the immediate and potentially serious consequences of very high or very low blood glucose. Monitoring also enables tighter blood glucose control, which decreases the long-term risks of diabetic complications.

Three keys to success in monitoring your blood sugar anywhere are:
  • Keeping your glucometer and supplies with you at all times so that you always have them when you need them
  • Making it a habit to check your blood sugar level by building it into your daily routine
  • Checking your glucometer's accuracy when you visit your doctor by comparing your results with your doctor's results
Why monitor your blood sugar
  • Monitoring your blood sugar level takes the guesswork out of your daily diabetes care.
  • Testing your blood sugar at home helps you know when your blood sugar is low. Low blood sugar can lead to an emergency. If your blood sugar drops just below the level that is safe for your body and you quickly eat something containing sugar, your blood sugar will rise and you may prevent an emergency.
  • When your blood sugar is high: Over time, high blood sugar levels cause permanent damage to the eyes, heart, kidneys, blood vessels, and nerves. If you are pregnant, high blood sugar levels may cause problems for you and your baby. Low blood sugar levels are even more dangerous for your fetus.
  • What your blood sugar level is before a meal: If you take short-acting insulin, you can use these results to determine how much insulin to take.
  • How different types of food affect your blood sugar.
  • How exercise affects your blood sugar: Exercise usually lowers your blood sugar level.
  • What your blood sugar is when you are ill: Severe illness or stress usually causes higher blood sugar levels.
  • When your insulin dose may need adjusting: If your blood sur levels remain high over a period of time or you have frequent low blood sugar, your insulin dose may need adjustment.
Studies have proven that people with Type 1 and 2 diabetes who maintain normal or near normal blood glucose levels have a lower risk of diabetes-related complications. The frequency of monitoring; Seven time profile is ideally recommended.

Targets (more than 50% values within target range)
Age less than six years 100-200 mg/dl before every meal and bedtime
Age six to twelve years 80-180 mg/dl before every meal and bedtime
Age more than twelve years 80-140 mg/dl before every meal
Less then 160 mg/dl after two hours of each meal
100-160 before bed.

How to Test
  • Wash hands with soap and clean water. Dry hands.
  • Prepare the lancing device by inserting a fresh lancet. Lancets that are used more than once are not as sharp as a new lancet, and can cause more pain , injury to the skin and infections.
  • Prepare the blood glucose meter and test strip (instructions for this depend upon the type of glucose meter used).
  • Use the lancing device to obtain a small drop of blood from the fingertip or alternate site (like the skin of the forearm). Alternate sites are often less painful than the fingertip. However, results from alternate sites are not as accurate as fingertip samples when the blood glucose is rising or falling rapidly.
  • Patients who have difficulty getting a good drop of blood from the fingertip can try rinsing the fingers with warm water, shaking the hand below the waist, or squeezing ("milking") the fingertip.
  • Apply the blood drop to the test strip in the blood glucose meter. The results will be displayed on the meter after several seconds.
  • Dispose off the used lancet in a puncture resistant sharp container or any glass jar (not in household trash because any one can be hurt by it).
