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

Insulin hypoglycemia test in volunteers without diabetes mellitus or any other metabolic diseases (n=59). One of the devices is indicated as the EZ Smart. However, this is a trademark used by Tyson Bio for a number of its devices. The actual device used is not stated in the paper. All of the home BGMs failed to sense hypoglycemia to some extent. The unspecified Tyson Bio EZ Smart device was significantly inferior to the Roche Accu-Chek Go, the Ascensia (Bayer) Contour TS, the Abbott Optium Xceed and the J&J OneTouch Select in the critical error Zone D of the Clarke Error Grid. The OneTouch Select was significantly inferior in error Zone B while the Accu-Chek Go, the Contour TS, and the Optium Xceed had similar performances and were significantly better than the other two BGMs.
