Adverse pregnancy outcomes in hypertensive patients: predictive value of protein concentration versus total protein.

Objectives: To compare the predictive value of protein concentration in a twenty-four hour urine collection to the conventional total protein in a twenty-four hour urine collection for adverse pregnancy outcomes in hypertensive patients.

Study Design: Retrospective cohort study. Hypertensive patients ≥20 weeks estimated gestational age (EGA) who completed twenty-four hour urine protein collections were identified; antepartum and delivery data were examined.
