ISG-BIO04528662001. ACCU-CHEK Aviva Test Strips help make every single strip count by making it easy to test right the first time. Test strips quickly attract and absorb a tiny blood drop for easier blood application. The wide-mouth dosing area isesigned so you can fill the strip on the very first try. You need just 0.6 microliters of blood for accurate testing every time. A larer, wider strip is easy to use for people of all ages, and for those with arthritis. The eight electrodes at the top of each strip work with meter technology to help the system detect and prevent unreliable results.
