Serum Uric Acid Measurement in Women With Hypertensive Disorders of Pregnancy

A 27-year-old asymptomatic primigravid woman at 36 weeks of gestation is evaluated in the labor and delivery unit with new-onset hypertension of 145/92 mm Hg (with similar measurements 4 hours apart). A spot urine protein/creatinine ratio is 0.35, serum transaminases and creatinine level are normal, and uric acid is 6.0 mg/dL (upper limit of normal for adult woman is 6.0 mg/dL but typically 4-5 mg/dL in the third trimester). Antenatal fetal testing and growth on ultrasound scan are reassuring. She is discharged for home management and ultimately delivered at 37 weeks of gestation for preeclampsia without severe features.
