Bloodless Bloodglucose Measurement September 22. 2000; Precision and Accuracy of the Diasensor 1000: Comparison of invasive and noninvasive methods for measuring blood glucose. Last update January 01. 2005 The trial has been made to find an answer to the following questions: 1. How can the precision of the Diasensor 1000 be determined ? 2. How can the relative accuracy of the Diasensor 1000 be determined ? 3. Which devices have been used for the trial ? 4. In which sequence were the measurements made ? 5. How many measurements have been made ? 6. How do the devices look like, used for measurement and how does the place look like, where the measurements have been made? 7. How precisely are the measurements made with Reflolux S, an usual blood glucose measurement device as used for blood glucose self control from diabetics in Germany. 8. How precisely are the measurements made with HemoCue, a measurement device mainly used in clinics and from physicians, which was used for the Calibration of the Diasensor 1000 ? 9. How precisely are the measurements made with the Diasensor 1000? 10. Which relative accuracy exists between the invasive HemoCue meter and the non-invasive Diasensor 1000 ? 11. What is the effect of calm paperwork onto the relative accuracy of the HemoCue and the Diasensor 1000? 12. What is the effect of slow movement and 20 minutes sports in the afternoon on a hometrainer onto the relative accuracy of the HemoCue and the Diasensor 1000 ? 13. What is the effect of stress onto the relative accuracy of the Diasensor 1000 and the HemoCue device ? 14. What is the effect of unusual strong movement, 2 hours of sports on a hometrainer, onto the relative accuracy of the Diasensor 1000 and the HemoCue device ? 15. Can the Diasensor 1000 be used to give a warning if the hypoglycaemic blood glucose region is reached ? and 16. What is the effect of alcoholics to the relative accuracy of the Diasensor 1000 ? 17. For which purpose can the Diasensor 1000 be used ? 18. What causes the declining of the correlation shown under certain circumstances? 19. What is the reason why the Diasensor 1000 can not be used to detect or monitor for hypoglycenmie ( low blood sugar) ? 20. Which possibilities exist to solve the problem shown and to improve the relative accuracy of the non-invasive measurement ?
