Evaluating the Accuracy of Continuous Glucose Monitoring by the Patient trough Continuous Glucose Error Grid Analysis
2011
Abstract
The aim of the study is to compare the difference between the accuracy declared by the producer of continuous glucose determination using the MiniMed Paradigm REAL-Time system with the results achieved by patients in real life. The glucose sensor evaluates the catalytic transformation of glucose (enzyme glucose dehydrogenase) to hydrogen peroxide, the concentration of which is electrochemically evaluated.
The accuracy of measurement was determined by Clarke Error Grid Analysis. It can be concluded that in normal glycaemia (4.4 to 10.0 mmol/l) the measurements realized by the patients are more accurate than it is supposed by the producer, opposite to the cases of hypoglycaemia or hyperglycaemia.
