How Accurate are Painless Glucose Monitors?
Studies have shown that readings will vary when alternate-site testing is done on other areas of the body. This is partially due to the circulation of the blood. While painless glucose monitors well for diabetics with relatively stable glucose levels, the fingertips will provide a more accurate reading when glucose levels are rapidly changing. This is important to understand when you are determining your insulin injections or watching for hypoglycemia.
