The Accu-Chek Comfort Curve strips are one of the best-selling diabetes test strips used in hospitals. Shaped to fit the curve of your finger and requiring smaller sample sizes of blood, these strips aim to maximize comfort and ease pain. The large indicator window feature allows for easy reading and comprehension. These glucose test strips are uniquely designed to be touchable: there is no need to use a new test strip to retest, because if not enough blood is applied for accurate results, the window will tell you. If the yellow window indicator is full, enough blood has been applied for testing. If not, more blood can be reapplied to the same strip, up to 15 seconds later. They are also fully equipped with top of the line electrodes with palladium to ensure their results are accurate. The Accu-Chek Comfort Curve strips are even active in extreme temperatures between 57 and 104 degrees Fahrenheit. Designed for use with the Accu-Chek Advantage or the Accu-Chek Complete, these strips are easy to use and extremely convenient. They make blood sugar testing quicker and more efficient than before.
