The effect of sampling of capillary blood on filter paper on the later analysis for glucose was evaluated. The method was found to be simple and reliable. Determination at the central laboratory of glucose in blood collected onto filter paper and comparison of the results with those obtained with test strips read in reflectometers at outpatient units was easy. Collecting duplicate samples on filter paper facilitates quality control by avoiding the complications that arise from using quality-control solutions that are not directly comparable with fresh blood and it avoids the disturbances of test strip chemistry attributable to the glycolysis inhibitors added to blood samples intended for quality control. [The use of this technique in diabetics to assess glucose control was described.].
