Correct answer: A. Serum creatinine and estimated renal function
- A. Serum creatinine and estimated renal function
- B. Serum amylase and faecal occult blood

Lithium is eliminated mainly by the kidneys, so renal function should be assessed before and during treatment. Abnormal renal function may require a different treatment plan or closer monitoring.
