Roche ACCU-CHEK Aviva Test Strips help make every strip count by making it easy to test right the first time. The Accu Chek Aviva Test strips quickly attract and absorb a tiny blood drop for easier blood application. The wide-mouth dosing area is designed so you can fill the strip on the very first try. To test with the Accu-Chek Aviva Strips, all you need is just 0.6 microliter of blood. A larger, wider strip is easy to use for people of all ages. The eight electrodes at the top of each Aviva strip work with the meter technology to help the system detect and prevent unreliable results.
