Blood Glucose Meter Accuracy

Blood glucose meters are invaluable instruments used in managing diabetes. But if your meter isn't accurate, it isn't fulfilling its purpose.

Below is a list of things that you can do to maximize your meter's efficiency.

Storage

Your meter should be in a protective case of sleeve when not in use. These are very delicate instruments that will not read properly if their calibration is off. Banging it around in a bag or in your pocket only offsets its ability to read.

Many diabetics do not realize that meters can become affected by outside components, too. Humidity and temperature are just two factors that can alter readouts. Your meter should be dry and within normal temperature ranges at all times. Storing it in a hot car during the summer is a no-no.

Cleanliness

Cleanliness is everything. This not only goes for the meter, but also the strips, too. Dust, dirt or even sweat can affect the validity of a reading. Considering how little the blood sample is being tested means very little room for error. Debris on the test strip taints the sample and can alter the readout.

Believe it or not, dirty hands will reduce the likelihood of a good reading. Think about when you get a shot: the first thing they do is to clean the skin with alcohol to ensure a sterile injection. Blood samples may not require sterilization, but the cleaner the entry is, the better.

Strips have an expiration date. By using outdated strips you risk getting an invalid reading. The condition of the strips also comes into play. If they aren't protected, they can become scratched, dented or the surface damaged. Any or all of these can reduce accuracy.
