Bayer® Ascensia Contour® Test Strips are for use with Ascensia Contour Meter. Formerly known as Ascensia Microfill Test Strips, the Contour Test Strips use Sip-in Sampling® Technology which require only a tiny drop of blood for an accurate reading. These test strips provide easy viewing of sample fill to ensure accurate results and fast testing. There is No Coding Required™ for the Ascensia Test Strip. This means you can open a new box of test strips and use them right away – no extra steps to take!
