What is considered proteinuria concern in pregnancy?

• A. Greater than 300 mg in 24-hour urine collection
• B. Greater than 1000 mg in 24-hour urine
• C. Greater than 50 mg in 24-hour urine
• D. Greater than 500 mg in 24-hour urine

Answer: (A)

Proteinuria signals potential preeclampsia in pregnancy, and the level that defines concern is 300 mg of protein in 24 hours. This amount reflects clinically meaningful renal involvement beyond normal physiologic protein leakage in pregnancy. When this level is present after 20 weeks’ gestation along with new-onset hypertension, it supports the diagnosis of preeclampsia. In practice, a 24-hour urine collection is the standard way to quantify this, though a protein/creatinine ratio ≥0.3 or a dipstick showing 1+ can indicate proteinuria and may prompt confirmation. Values like 50 mg are not considered concerning, while 500 mg or 1000 mg indicate more protein loss, but the recognized threshold used to raise concern is 300 mg in 24 hours.
