The glomerular filtration rate (GFR) can be determined from: A) Urinary flow rate (V), plasma P-aminohippuric acid (PAH) concentration (P_PAH) and urinary PAH concentration (U_PAH) B) Urinary flow rate (V), plasma arginine vasopressin (AVP) concentration (P_AVP) and urinary AVP concentration (U_AVP) C) Urinary flow rate (V), plasma creatinine concentration (P_creatinine) and urinary creatinine concentration (U_creatinine) D) Urinary flow rate (V), plasma urea concentration (P_urea) and urinary urea concentration (U_urea) E) Urinary flow rate (V), plasma insulin concentration (P_insulin) and urinary insulin concentration (U_insulin)

Question

Quizplus · Accepted Answer

The glomerular filtration rate (GFR) is most commonly estimated using the urinary flow rate (V), plasma creatinine concentration, and urinary creatinine concentration. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys and is a standard marker used to estimate GFR.
