Abstract
This study was carried out to obtain exact blood glucose differences due to samples, analytical methods and instruments. Glucose values obtained with autoanalyzer having deproteinizing system were lower than those obtained by the instrument without deproteinizing system, but the difference was less when the analyzer had no deproteinizing procedure but a dual wave length system. The difference between Hoffman's method and glucose-oxidase method was 10mg/dl. Plasma glucose values were higher than those of whole blood and the difference varied with glucose values-blood glucose analysis
