Ascensia Contour Next Link (Bayer)

Description:

The Ascensia Contour Next Link (Bayer) is an automatic blood glucose meter. The accuracy of its blood glucose measurement technology has yet to be proven to MDR requirements. 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:

While the technology used in the Ascensia Contour Next Link (Bayer), to measure blood glucose, has been assessed, the results of the study have not been published and cannot be verified.

Recommendations:

	Accuracy Assessment	Recommendation	Basis
BG	Medaval	None	While a clinical validation is claimed, it cannot be checked properly.
BG	Institute of Health Economics (CA)	General use	No evidence provided

Measurements from the Ascensia (Bayer) Contour Next Link are compared to those from the J&J OneTouch UltraLink and the Nova Max Link, though not in a formal validation.

Comparison in children and adolescents with T1DM (aged 4 to 18 years) (along with the Roche Accu-Chek Mobile and the JnJ LifeScan OneTouch Verio IQ) to the Abbott FreeStyle Libre Flash (n=26). Authors conclude reasonable agreement but with large interindividual variability and that further studies in children are imperative.
