Which of the following renal function parameters characteristically INCREASES during normal physiological pregnancy?
- A.Serum creatinine
- B.Serum urea (blood urea nitrogen)
- C.Glomerular filtration rate (GFR)Correct answer
- D.Serum uric acid
Solution
Renal plasma flow and glomerular filtration rate (GFR) increase by up to 50% early in pregnancy (by the end of the first trimester). Consequently, the baseline values of serum creatinine, urea, and uric acid all fall. An upper limit of normal for serum creatinine in non-pregnant women (e.g., 1.0 mg/dL) may indicate renal impairment in a pregnant woman.
