When persons with diabetes use miscoded blood glucose meters to determine how much insulin to take, significant errors in insulin dose can result that may potentially lead to short- and long-term health complications, according to a new study published in the Journal of Diabetes Science and Technology. The study also showed that meters with "No Coding" technology (meters that automatically set the correct code anytime a test strip is inserted) gave a superior performance over meters used in this study that had been correctly coded manually. This also translated into a lower probability of insulin dose error. Coding is the process by which a blood glucose meter is matched to each new box of test strips being used.
