Prodigy No Coding Test Strips work with the Prodigy AutoCode, Pocket, and Voice meters. The 3 lead technology allows the meters to test only when there is enough blood on the test strip, saving the user test strips and money. The capillary action automatically draws the blood sample into the test strip. Prodigy No Coding test strips do not use GDH-PQQ technology and are approved for alternate site testing. Glucose oxidase technology allows for safer and more accurate results.
