Ascensia Contour Next USB (Bayer)

Description:

The Ascensia Contour Next USB (Bayer) is an automatic blood glucose meter. Its blood glucose measurement technology has been proven to be accurate, with a 3-star Medaval rating. Blood glucose measurements are normally taken from the finger but alternative site testing is allowed. It is intended for both professional use and self-measurement. This device has been discontinued by the manufacturer but may be available through certain outlets.

Assessment:

The technology used in the Ascensia Contour Next USB (Bayer), to measure blood glucose, is among the best rated for accuracy by Medaval Ltd. It has passed in two clinical validation studies, between general and specific populations, according to recognised standard protocols, as published in peer-reviewed publications.
