Calculate the clearance of substance X, assuming the concentration of X in the urine is 5 mmol/l, that 1 liter of urine is produced per day and that the concentration of X in the plasma is 1 mmol/l.
What will be an ideal response?
Answer: Clearance = urine concentration * urine volume / plasma concentration
Clearance = 5 mmol/l * 1 liter/day / 1 mmol/l = 5 liters/day
