The technology used in the Nipro TRUEtrack, to measure blood glucose, has failed in a clinical validation study, in a general population, according to a recognised standard protocol, as published in a peer-reviewed publication. It has also been assessed, in a general population, according to a non-standard protocol.

Measurements from the Nipro Truetrack are compared to those from the Bayer Contour Next and, indirectly, the Roche Accu-Chek Aviva Nano, the Abbott FreeStyle Lite, the J&J LifeScan OneTouch Ultra 2 and the J&J LifeScan OneTouch Verio Pro, though not in a formal validation.
