What is the significant threshold for proteinuria indicating preeclampsia?

• A. ≥ 300 mg/24 hr
• B. ≥ 1000 mg/24 hr
• C. ≥ 150 mg/24 hr
• D. ≥ 500 mg/24 hr

Answer: (A)

A significant threshold for proteinuria indicating preeclampsia is 300 mg of protein in a 24-hour urine collection. This level is considered diagnostic for preeclampsia, particularly when accompanied by hypertension. The rationale behind this threshold is that it reflects a substantial impairment in kidney function due to the underlying pathophysiological changes associated with preeclampsia, which can lead to serious maternal and fetal complications if not managed appropriately. Monitoring protein levels is crucial, as the presence of protein in the urine suggests that the kidneys are adversely affected, and this can signify a more widespread systemic issue associated with the condition. While lower thresholds for proteinuria can indicate other conditions related to pregnancy, such as gestational hypertension, the 300 mg/24 hr level is the standard benchmark used in clinical practice to diagnose preeclampsia effectively.
