[Serial determination of HbA1 or the oral glucose test in the adequate evaluation of fetal growth?].

The authors compared sequential HbA1 levels with the results obtained by oral glucose tolerance test (O.G.T.T.) with the purpose of detecting the confidence limit of each test regarding the glucose control in pregnant women. HbA1 detection showed more sensitivity than O.G.T.T. in detecting maternal impaired glucose control and in distinguishing between a metabolic or a genetic feto-neonatal macrosomia.
