Abstract
Introduction The rise and fall of the blood glucose concentration following oral or intravenous administration of glucose--' the glucose tolerance curve ' has long been widely used both clinically and experimentally in animals and man as an index of the efficiency of the mechanisms regulating the concentration of glucose in the blood. Many of the published data are conflicting, and the variation in method95 employed by different workers makes comparison of results impossible. Even when the same procedure has been used in apparently similar circumstances, different results have often been obtained. Lack of general agreement about either the evaluation or the interpretation of the different blood glucose curves resulting from any of the various techniques employed increases the confusion. Moreover, it is insufficiently recognized that glucose tolerance tests can provide only limited information about carbohydrate metabolism, and unwarranted deductions have all too frequently been made from them. This situation is due to several factors:
