How to test, read, and use blood sugar test strips is explained here.

Blood glucose monitoring is an important part of diabetes treatment for both type 1 and type 2 diabetic patients (diabetes mellitus). Without the assistance of a healthcare expert, most persons with diabetes monitor their blood glucose levels regularly at home. Here's a quick rundown of how glucose meters and glucose testing function.

It's time to take a blood sugar test. On the table is your glucose meter. You place a new test strip in your lancing device, load a new lancet into your lancing device, snap the tiny needle into the side of your finger, and squeeze until a small quantity of blood forms a red dome.

You drop of a blood to the strip's edge and wait for your glucose monitor to count down to reveal a real-time blood glucose reading. A number with significance. That number has the potential to alter the trajectory of your entire day. It could perhaps only be a temporary roadblock until the next finger-stick.

You did an excellent job! You've done your part in diabetes control and self-monitoring. Have you ever wondered how this important diabetes technology functions?

1. How your blood sugar is measured by your glucose meter

A capillary in blood glucose test strips suctions the blood into the test strip. The blood sample is combined with a glucose oxidase enzyme at an enzyme electrode, and the glucose meter generates an electrical current. The amount of glucose in the blood sample is proportional to the charge going through the electrode. So, if your test results show 90 mg/dL, your blood contains 90 milligrams of glucose per deciliter.

2. Alternative site testing

Because of the large concentration of nerves in the tips of the fingers, they are extremely sensitive. Many people draw blood from different places to escape the agony. Due to the highly precise findings from these blood glucose readings, most blood glucose meters were designed to be used with capillary blood collected from a finger prick.

Alternate site testing (AST) has been approved for some meters, including all of the meters we sell. AST is blood obtained from sites other than your fingertips, such as your palm or arm.

If you're interested in AST, check the instructions on your meter to see if it's approved for alternate site testing before making the switch.

3. Accuracy of a glucose meter

When you use a Glucometer to test your blood sugar, the result gives you an estimate of how much glucose is in your blood. The FDA has a medical device accuracy criterion for all glucose monitoring devices, which states that glucose meters must show values that are within 20% of a laboratory result 99 percent of the time (ours is within 15 percent, 99 percent of the time).

Temperature, amounts of other chemicals (such as ascorbic acid) in your blood, traces of other elements on your skin (such as food residue), water, heat, and the age of your test strips (check expiration date) are all factors that can affect the accuracy of your blood glucose monitor's results.

4. Why control solution is important

You can see why a control solution is vital once you understand the process. The control solution ensures that the enzymes on the test strips have not been harmed. As previously stated, the enzyme on test strips is extremely susceptible to environmental influences.

It's difficult to know whether environmental conditions have changed the enzymes on test strips once they've been transported from the plant. If one is affected, the entire batch has been dispatched.

To ensure that your strips are in good condition, use a control solution on the first strip you draw from a new container.
