[Problems of self-monitoring of blood glucose (SMBG) and right drawing blood methods--the impact that technique at the time of the blood glucose self puncture drawing blood and part give measurements].

Devices for self monitoring of blood glucose (SMBG) are used by diabetic patients themselves. Evaluation of the environmental temperature during use by patients showed the importance of the temperature environment. When measurement is performed at a temperature outside the measurement temperature range, a function to display errors or does not display measurement values is indispensable. Measures to reduce puncture pain in SMBG include use of a thin needle, shallow puncturing, and the selection of the palm or forearm instead of the fingertip as a puncture site. Using these measures to reduce puncture pain, the blood volume required for measurement is often difficult to collect. Therefore, the puncture site is massaged or squeezed. However, these actions were reported to have serious influences on measurement values. Changes in the blood glucose and Ht levels and the hemolysis phenomenon were confirmed as the influences of the massaging or squeezing method. The correct blood collection method free of such influences is blood sampling from the fingertip using the pushing out method.
