In 199 normotensive pregnant women at 20 and 30 weeks of gestation, a fasting urinary albumin/creatinine ratio (FU Alb/Cr) was evaluated to predict pregnancy-induced hypertension (PIH). FU Alb/Cr in patients destined to develop PIH was significantly high compared to that in normotensive women. When FU Alb/Cr of more than 16 was considered to represent a positive test result, the negative predictive value was 94% and 96%, respectively. FU Alb/Cr is a useful screening tool for PIH.
