Background: Glucose is primary source of energy for body cells so body naturally regulates blood glucose by homeostatic mechanism. It is important to monitor blood glucose especially in diabetic patients to prevent complications. As laboratory method is time consuming, more painful and require expert phlebotomist so there is a need for accurate, easy and quicker method of estimation. Therefore use of glucometer has been greatly increased and is helpful for self management of blood glucose at home. Estimation of blood glucose is influenced by many factors like origin and type of sample and method of analysis, so we are doing this study to know the accuracy and reliability of glucometer in comparison with laboratory method.
Aim: 1] To Compare blood glucose estimation by glucometer and laboratory method. 2] To find out variation in percentage in results and determine accuracy of glucometer compared to laboratory method
Materials and methods: 100 patients attending OPD of our hospital were selected and capillary blood glucose estimation was done by glucometer and venous blood glucose estimation by GOD-POD method on semiautoanalyzer in our laboratory irrespective of patients diabetic or non-diabetic status.
Results: Mean capillary blood glucose done by glucometer was 10.72% higher than venous blood glucose done by GOD-POD method in fasting samples, 15.92% higher in postmeal and 16.67% higher in random blood samples. Non-significant variations were found between results of glucometer and laboratory methods.
Conclusion: As result of glucometer and laboratory method shows non-significant but slight difference, glucometer is feasible alternative to laboratory method as more convenient and quicker results are obtained and can be used for self management of blood sugar at home.
