Diabetes treatment is made possible by constantly monitoring blood sugar levels. Diabetic patients can do this at home with a diabetes testing machine or blood glucose meter that measures glucose levels in the blood.
To test for your blood sugar level, a very small amount of blood is taken from your finger. Almost all glucometers use a test strip to absorb the blood droplet for the machine to analyze. The machine comes with a lancet device that makes a small incision in the finger to draw blood for testing.
There are many different makes and models of blood sugar meters but there are only two basic types. One is a small portable glucometer with test strips stored inside the machine. When the diabetes testing machine is switched on, a test strip is exposed through a small slot. The blood droplet is transferred to the strip for testing.
The second type of glucometer uses external test strips which are inserted into a slot in the machine for testing.
