Microalbuminuria in normal pregnancy: Relation to obstetric factors

Summary

Urine samples, negative for protein on ‘dipstick’ testing (< 300 mg/l), were collected from women at 28–41 weeks of pregnancy and analysed for albumin and creatinine. Compared with a non-pregnant control group, there was no significant difference in the urine albumin:creatinine ratio at 28–31, 32–35, 36–37 or 37–41 weeks. Nor was there any difference in the ratio in relation to maternal age and parity or fetal sex and birth weight. The results suggest that pregnancy in general has no effect on albumin excretion.
