Overview
Strong progress of analytical and information technologies causes lot of essential changes for monitoring therapy in diabetes. Our communication deals with brief but exhaustive information about them. Namely on the analytical tools, quality assessment, clinical interpretation. Namely information on glucometers, devices for continual glucose measurement and the relations to HbA1c. Direct access to recent literature sources including guidelines of IFCC working group of CGM are the part of communication, too. The aim of publication is to create information bridge among patients, physicians and clinical laboratories.
Keywords:
diabetes – HbA1c – standardization – therapy measurement – glucometers – CGM and its parameters
