A PAH test result showing a renal plasma flow of 400 mL/min:
A) Is a normal result
B) May be falsely decreased from impaired tubular secretion
C) Should be corrected to correspond to the patient's body size
D) Indicates glomerular filtration of PAH

Question

Quizplus · Accepted Answer

Para-aminohippuric acid (PAH) is used to estimate renal plasma flow, and a result of 400 mL/min is lower than the normal range (around 600-700 mL/min). This may indicate impaired tubular secretion, leading to a falsely decreased result.
