An important medical study known as the DCCT (Diabetes Control and Complications Trial) concluded that the use of SMBG in tight control of levels of blood sugar greatly lessened the possibility of getting complications related to diabetes. After the publication of the study in 1993, SMBG guidelines have been developed. Testing at home as a regular occurrence is now encouraged.


For diabetics who have hypoglycemic unawareness, testing for blood sugar at home is necessary. Such diabetics are unaware of the usual signs such as a fast heartbeat, worry, unsteadiness, a dizzy feeling and irritability, which warn them that their blood glucose levels are getting too low.

I don’€™t like the idea of sticking a needle into myself. Why not just test my urine for sugar?

It can be done but it will not be of much use to you if you really want to have your diabetes under control. You see, urine stays too long in the bladder to give an accurate measurement of the sugar in it. Furthermore, there must be more than 180 mg/dL of glucose in the blood to have it shown in the urine. And possibly life threatening low levels of blood glucose cannot be detected.

How often and when is testing needed

People wonder when they should test. There are those who test only once, at the time they awaken. Some test in the morning, at night, also before as well as after meals, testing many times each day. Generally, it is advisable to check your levels of blood sugar as often as possible after your first diagnosis of diabetes so that you can find out how different foods, activities, medications and insulin affect your glucose levels. You also need to check just as often to see how good treatment changes have been.

In order to make the right changes to insulin dosage, blood sugar checks need to be done frequently. Those diabetics who have the brittle diabetes condition in which their sugar levels are not constant, always changing without any signs of warning should also test very often.


You must check your blood glucose level immediately if you perceived it to be low. It can be treated by eating processed or refined carbohydrates which amount to 15 grams, have a 15 minute wait before testing again. Should you find your blood glucose not yet in the range which is safe, go through the above treatment again. Should you be unable to find your monitor when you perceive your blood glucose level to be low, treat it anyway and have it checked later.

When to check

It is recommended by the ADA (American Diabetes Association) that diabetics check a minimum twice a day if you are using insulin pumps or are having injections of multiple insulins. In fact, they should test more often since the accurate results of the tests are important in deciding on the correct dosage and making sure the blood glucose levels are in a range which is safe.

For type 2 diabetics who do not need insulin and type 1 diabetics who inject insulin only once, maybe two times each day, no particular recommendations are given by the ADA (American Diabetes Association). However, even for these people, self-monitoring of blood glucose levels is the tool to give instant feedback on the effects food, exercise, medication and other factors in the environment on blood glucose. Therefore, frequent self-monitoring ought to be done to reach targeted blood glucose results although testing supplies are expensive.
