# is the GFR of each patient? Patient 1: V = rate of urine production (ml/min) = 1.2 U_inulin = amount of inulin excreted in urine each minute (mg/mL) = 15.8

is the GFR of each patient? Patient 1: V = rate of urine production (ml/min) = 1.2 U_inulin = amount of inulin excreted in urine each minute (mg/mL) = 15.8 P_inulin = plasma inulin (mg/mL) = 0.151 Patient 2: V = rate of urine production (ml/min) = 0.75 U_inulin = amount of inulin excreted in urine each minute (mg/mL) = 25.2 P_inulin = plasma inulin (mg/mL) = 0.155 Patient 3: V = rate of urine production (ml/min) = 15 U_inulin = amount of inulin excreted in urine each minute (mg/mL) = 1.23 P_inulin = plasma inulin (mg/mL) = 0.154 Transcribed Image Text: Substance, S, has renal clearance CS is the same as the amount of S excreted in
urine each minute, US.
When a substance is only filtered its clearance value equals the GFR (inulin, not
insulin, is the standard).
Substances both filtered and secreted will have clearances >GFR.
Reabsorbed substances have a clearance
