RESUMO
Blood samples were collected from 30 subjects. To a portion from each sample was added Fluoride/Ethylene Diamine Tetra Acetate (E.D.T.A) to inhibit glycolysis and clotting. The remaining portions were allowed to clot without any inhibitor. On subjecting to glucose concentration testing, the portions without the inhibitor showed a decline in the glucose level of 8 mg/dl (0.44 mmol/l) in the first hour and of 7 mg/dl (0.39 mmol/l) per hour in the next two hours. It is re-emphasised that a glycolysis inhibitor should always be added to blood samples drawn for glucose level testing. Otherwise, the reported results could be misleading.

The Precision Quantum-in-dium (Q.I.D.) Glucometer was used to determine the glucose concentrations of 38 human blood samples. The same samples were also run on the OPERA Chemistry Autoanalyzer 2010 system. More than 44% of the glucometer reports had a difference of greater than 15% from the respective autoanalyzer reports. The calibration of the glucometer could be the source of the error and an improvement is recommended.
