Cnoga TensorTip Combo

Description:

The Cnoga TensorTip Combo is an automatic blood glucose meter. Although its blood glucose measurement technology has been evaluated, it is not possible to base a determination on its accuracy from this research. Blood glucose measurements are taken from the finger. It is intended for self-measurement and home use.

Assessment:

The technology used in the Cnoga TensorTip Combo, to measure blood glucose, has been assessed, in a general population, according to a non-standard protocol.

Recommendations:

	Accuracy Assessment	Recommendation	Basis
BG	Medaval	None	When an evaluation is carried out using a non-standard protocol, no inference can be made on accuracy based on a standard protocol.

After appropriate individual calibration of the noninvasive technology, both the noninvasive and the invasive Cnoga TensorTip-Combo components tracked tissue and blood glucose values reliably, respectively. This may enable patients with diabetes to monitor their glucose levels frequently, reliably and, most of all, pain-free.

Measurements from the Cnoga TensorTip Combo are compared to those from the Roche Accu-Chek Performa, the Ascensia Contour, the Abbott FreeStyle and the Abbott i-STAT, though not in a formal validation.
