Abstract Background: Poisoning is one of the most common medical presentations in a hospital. Results: The mean of capillary blood glucose was Conclusion: Using venous blood sample and measuring the glucose level in it by glucometer is an acceptable and advisable method, and capillary blood glucose measurement by using glucometer is not recommended for patients in coma.

Implementation will do much to harmonize glucose testing and should prevent many of the most serious errors of interpretation. Investigation of discordance between glucose results obtained at the point of care with results obtained in the central laboratory must take account of sample type, detail of measuring systems, characteristics of the patient and possible ways in which each of these three elements might interact to affect glucose result.

January Measurement of circulating glucose: The problem of inconsistent sample and methodology. THE SAMPLE Glucose concentration might be measured using a whole blood sample either venous, arterial or capillary ; or a plasma sample recovered after centrifugation of anticoagulated whole blood either venous, arterial or capillary ; or a serum sample recovered after centrifugation of non-anticoagulated whole blood either venous, arterial or capillary.
Whole blood glucose concentration is determined by three parameters: plasma glucose concentration, pl gluc; red cell glucose concentration, rc gluc approximately Difference between venous plasma and venous serum glucose concentration The glucose concentration of venous plasma and venous serum should theoretically be the same. FIGURE 1: Glucose concentration is sample dependent adapted from ref 4 Note the the difference between capillary blood glucose and venous sample types depends on the time since last meal.
Venous plasma - the reference sample Of all the clinical contexts in which glucose is measured, diagnosis of diabetes is the one that demands greatest accuracy and precision. Hexokinase methods In the central laboratory, glucose-measuring platforms on automated analyzers are most frequently based on the enzyme hexokinase [16]. FIGURE 2a: Glucose measurement - hexokinase Glucose oxidase - photometric and amperometric Both laboratory-based and point-of-care glucose measuring systems utilize the enzyme glucose oxidase.
FIGURE 2b: Glucose measurement - glucose oxidase The consumption of oxygen or production of hydrogen peroxide that results from glucose oxidase action allows amperometric measurement of glucose. Glucose dehydrogenase - the HemoCue analyzer Glucose measuring systems based on glucose dehydrogenase are fewer in number than those based on glucose oxidase or hexokinase but the HemoCue glucose analyzer is an example of one that does.

It is well established that the education and training of glucometer operators is important to obtain accurate results. The training status of all glucometer operators included healthcare providers and family members, but details remained unknown. Raine et al. Significant insulin dose errors may occur if blood glucose results are obtained from miscoded meters.
