Insulin receptor binding to erythrocytes in the first half of pregnancy is increased in healthy pregnant women as compared with non-pregnant or gestational diabetic women

Abstract Insulin binding to erythrocytes was measured longitudinally by a competitive radioreceptor assay in 21 healthy pregnant (HP) and 20 well-controlled gestational diabetic women (GD) in 4-week intervals throughout pregnancy and at day 4 post-partum. Maximum insulin binding (maxbdg) at weeks 8–14 was increased ( P
