A serum creatinine level primarily assesses which organ's function?
Show answer and explanation
Correct answer: D. Kidney
- A. Liver function is assessed by AST, ALT, bilirubin, albumin and INR.
- B. Pancreatic function is assessed by amylase, lipase and glucose.
- C. Cardiac markers are troponin, BNP and CK-MB.
- D. Correct. Creatinine is a muscle metabolism byproduct cleared almost entirely by glomerular filtration. A rise indicates reduced GFR and mandates dose adjustment of renally excreted drugs — amoxicillin, acyclovir and NSAIDs among them.
