If clearance of a drug equals the CFR, it implies that
Drug is reabsorbed in renal tubules
Drug is secreted into renal tubules
Drug is neither secreted or reabsorbed in renal tubules
None of the above
Clearance = GFR, If there is no secretion or reabsorption in renal tubules.
Clearance > GFR, there is net tubular secretion.
Clearance < GFR, there is net tubular reabsoption.
