Using Expired Test Strips
While they last longer than grocery store produce, test strips can expire. These small plastic strips are a crucial key to diabetic care, as the chemical known as glucose oxidase turns your blood into gluconic acid and turns your sugar into electricity. The algorithm then works out the blood sugar levels by reading the difference in current. It’s imperative to date when they were opened and keep an eye on the expiration date. When they expire or have become damaged, they will give false readings that will cause you to over-treat or under-treat your blood sugar. Store your glucose strips as directed on the vial and avoid shaking them around.
