Proteinuria amount associated with signs of preeclampsia is greater than:

Proteinuria amount associated with signs of preeclampsia is greater than:

• A. > 300 mg of protein in urine in 24 hours
• B. > 1 g in 24 hours
• C. < 300 mg in 24 hours
• D. No protein required

Answer: (A)

Preeclampsia is diagnosed when new-onset hypertension after 20 weeks gestation is accompanied by protein in the urine. The usual threshold for proteinuria is 300 mg in a 24-hour urine collection. So, when urine protein exceeds 300 mg per day in the setting of high blood pressure, preeclampsia is suspected and managed as such. Heavier proteinuria, like greater than 1 g per day, can occur and often signals more severe disease, but the diagnostic cut-off is 300 mg per 24 hours or more. If no protein is detected, preeclampsia is less likely unless there are other signs of end-organ dysfunction that fulfill the diagnosis. In practice, a spot protein-to-creatinine ratio ≥0.3 can also be used if a 24-hour collection isn’t feasible, though it’s less precise.
