Elevated creatinine level above which threshold is considered a severe feature of preeclampsia?

• A. Greater than 1.1 mg/dL
• B. Greater than 0.8 mg/dL
• C. Greater than 2.5 mg/dL
• D. Greater than 0.5 mg/dL

Answer: (A)

Renal involvement signals a severe feature of preeclampsia because reduced kidney function reflects systemic endothelial dysfunction and increases risk for maternal complications. In pregnancy, creatinine typically stays low due to increased glomerular filtration, so a rise to greater than 1.1 mg/dL indicates meaningful renal impairment. This threshold (greater than 1.1 mg/dL) is the standard criterion used clinically to classify severe features, and a doubling from baseline can also meet the criterion if there’s no prior kidney disease. Values like 0.8 or 0.5 mg/dL are within the expected pregnant range, while a very high level such as 2.5 mg/dL would clearly indicate severe renal dysfunction, but the defined threshold for severe features is 1.1 mg/dL (or a doubling from baseline).
