Abstract
A procedure for verifying the accuracy of a non-invasive blood glucose measurement instrument utilizes in vitro or invasive measurement instruments, the accuracy of which is independently verifiable. Several glucose readings are taken with each instrument at approximately the same times. The measurement data from the in vitro instrument is transferred to the non-invasive instrument where it is compared to the data regarding the non-invasive measurements. If the difference between the measurements of the respective instruments is within a preset range, the non-invasive instrument is permitted to be used for an additional period of time. However, if the difference is beyond an acceptable limit, then the non-invasive instrument is prevented from taking any additional measurements and must be serviced or repaired.
