A subject has a renal plasma flow of 660 mL min⁻¹ and a filtration fraction of 0.20. Inulin clearance measured in this subject is 120 mL min⁻¹. Assuming a haematocrit of 0.45, calculate the glomerular filtration rate (GFR) from the filtration fraction, compare it with the inulin clearance, and state whether the inulin measurement is within 10 % of the calculated GFR.

Answer Options

A. Calculated GFR = 120 mL min⁻¹; inulin clearance is within 10 % (acceptable).
Correct Answer B. Calculated GFR = 132 mL min⁻¹; inulin clearance is within 10 % (acceptable).
C. Calculated GFR = 132 mL min⁻¹; inulin clearance is not within 10 % (unacceptable).
D. Calculated GFR = 150 mL min⁻¹; inulin clearance is not within 10 % (unacceptable).
Correct Answer
B
Correct Option:
Calculated GFR = 132 mL min⁻¹; inulin clearance is within 10 % (acceptable).
