These test strips are made with the latest glucose oxidase technology to make the testing process easier, faster, and less painful. With the tiny blood sample that the capillary action of the strips automatically draws, the 3 lead technology enables compatible test meters to test only when there is enough blood on the test strip. This prevents false readings or wasted test strips. The test strips only need 0.7 microliter of blood, which means that you can test from alternative sites like your palm, forearm, upper arm, calf or thigh to reduce pain. Features: No Coding required! Works with all Prodigy meters. Approved for Alternate Site Testing (AST). Capillary action makes testing easy! Case of 300 (6 Boxes of 50)
