Two substances that can probably be used to determine filtration fraction are_______________?
Correct answer: A. Inulin and PAH
- A. Inulin and PAH
- B. Urea and diodrast
- C. PAH and Phenol red
- D. Inulin and mannitol
Explanation
Filtration fraction is calculated as GFR divided by renal plasma flow. Inulin clearance estimates GFR and PAH clearance estimates effective renal plasma flow, so these two substances are used together.
