TABLE 3.

Serum urea and creatinine levels in the studied population.

	n	Creatinine levels (mg/dL)		Urea levels (mg/dl)
		Before 20 wks of gestation	After 20 wks of gestation	Before 20 wks of gestation	After 20 wks of gestation
Uncomplicated pregnancies	810	0.52 ± 0.09	0.50 ± 0.09	0.18 ± 0.06	0.17 ± 0.07
Preeclampsia	40	0.54 ± 0.12	0.56 ± 0.13	0.17 ± 0.06	0.20 ± 0.07
Gestational hypertension	33	0.55 ± 0.12	0.54 ± 0.19	0.16 ± 0.07	0.15 ± 0.05
IUGR without preeclampsia	20	0.57 ± 0.11	0.63 ± 0.23	0.18 ± 0.05	0.20 ± 0.06

Values are mean ± SD. In all cases, serum urea and creatinine levels did not change throughout gestation (P > 0.05).
