Integrity Applications, Inc. announced that it has received CE Mark approval for a major enhancement to GlucoTrack, allowing for a user to perform the calibration process by themselves, without the need for a certified calibrator. The initial CE Mark approval received for GlucoTrack required a calibration process that took three hours to complete, required eight invasive finger stick reference measurements, needed to be repeated every thirty days and required a certified calibrator to perform the calibration. After a series of successful enhancements and approvals, the calibration process now takes just thirty minutes, requires just three invasive reference measurements, and needs to be repeated only once every six months. With self-calibration, a user can now perform this simplified process in the privacy and convenience of their own home.
