Introduction
The criteria that define pre-eclampsia have not changed over the past decade.1,2 These are: onset at .20 weeks’ gestational age of 24-hour proteinuria $30 mg/day or, if not available, a protein concentration $30 mg ($1+ on dipstick) in a minimum of two random urine samples collected at least 4–6 hours but no more than 7 days apart, a systolic blood pressure .140 mmHg or diastolic blood pressure $90 mmHg as measured twice, using an appropriate cuff, 4–6 hours and less than 7 days apart, and disappearance of all these abnormalities before the end of the 6th week postpartum. Nonetheless, some presentations of pregnancy-related hypertension combined with clinical or laboratory abnormalities or intrauterine growth restriction should also be considered as potential pre-eclampsia.
