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