Fingertips are sensitive because of the high concentration of nerves. To avoid the pain, many people draw blood from other areas. Most blood glucose meters were originally designed to be used with capillary blood taken from a finger prick due to the highly accurate results from these blood glucose readings.
Some meters, including all of the meters we carry, have been approved for alternate site testing AST , which is blood drawn from areas other than your fingertips, such as your palm or arm. If you are interested in AST, read your meter directions to find out if it's approved for alternate site testing before attempting to make the change. When you test your blood sugar using any glucometer the result shows you an estimate of the amount of glucose in your blood.
The U. Many factors can affect the accuracy of your blood glucose monitor's results, including temperature, levels of other substances such as ascorbic acid in your blood, traces of other elements on your skin such as food residue , water, heat, the age of your test strips check expiration dates , and many more. When you understand the process, you can see why control solution is important.
Control solution assists you in making sure that the enzymes on the test strips haven't been damaged. The enzyme on test strips is very sensitive to environmental factors, as previously explained. Once test strips are shipped from the factory it is difficult to ensure environmental factors have not affected the enzymes on the test strips. If one is affected, all are in that shipped batch. Use control solution on the first strip you pull from a new container to verify that yours are in good condition.

Blood droplet is put on test strip containing glucose oxidase , an enzyme that reacts to glucose in blood and an interface to an electrode in the meter 2.
When the strip is inserted into the meter, the flux of the glucose reaction generates an electrical signal.

This system tests your glucose level every 5 minutes throughout the day and night through a CGM, and automatically gives you the right amount of basal insulin , a long-acting insulin, through a separate insulin pump.
You will still need to test your blood with a glucose meter a few times a day. And you'll manually adjust the amount of insulin the pump delivers at mealtimes and when you need a correction dose.
The hybrid closed-loop system may free you from some of the daily tasks needed to keep your blood glucose stable—or help you sleep through the night without the need to wake and test your glucose or take medicine.
Talk with your health care provider about whether this system might be right for you. The NIDDK has funded — and continues to fund — several important studies on different types of artificial pancreas devices to better help people with type 1 diabetes manage their disease.
The devices may also help people with type 2 diabetes and gestational diabetes. The NIDDK translates and disseminates research findings to increase knowledge and understanding about health and disease among patients, health professionals, and the public.
