Inulin clearance closely resembles_____________?
Correct answer: A. G.F.R
- A. G.F.R
- B. Renal plasma flow
- C. Creatinine clearance
- D. P.A.H. clearance
Explanation
Inulin is freely filtered by the glomerulus and is neither reabsorbed nor secreted by renal tubules, so its clearance equals the glomerular filtration rate. Creatinine clearance is only an approximate estimate because a small amount is secreted.
