These diabetes test strips automatically calibrate the blood glucose meter each time new Ascensia Contour test strips are used so there is no coding required! Automatic calibration ensures accurate results every time with fewer steps. 
New "SIP-in Sampling" technology ensures the right amount of blood is quickly wicked onto the strip. The Ascensia Contour Test Strips need only a very small drop of blood for proper blood glucose test results. Just 0.6 microliters of blood are required for precise results. Alternate Site Testing: The Ascensia Contour test strips can be used for testing alternate sites, such as the palm, or forearm. Utilizing alternate site testing may reduce pain caused by repetitive testing on the same area.
