I did a test on glucometer after not eating anything for 9 hours and the readings were 111 , I did FBS lab test at the same time and the readings were 86 Similarly I did a glucometerer test after 2 hours of eating and readings were 144 and same time gave lab sample results of lab test were 125 for PPBS, am I diabetic or it's just the glucometerer that is showing high reading as the lab results are within non diabetic range, kindly advise on accuracy of glucometers
