Renal Clearance
|
C = UV/ P
C= clearance of x U= urine concentration of x P= plasma concentration of x V= urine flow rate |
|
Renal clearance compared to GFR
|
|
|
Glomerular filtration rate:
|
GFR = (U) (V/P) = C
Can use inulin to calculate
Creatinine clearance is an approximate measure of GFR |
|
What is the equation for effective renal plasma flow?
|
eRPF = (UPAH) ( V/PPAH) = CPAH
|
|
What is renal blood flow if renal plasma flow is known?
|
RBF = RPF/ (1-Hct)
1-Htc : volume flowing through kidneys that is plasms |
|
Filtration fraction
|
FF= GFR/ RPF
|
|
How do you calculate resorption and secretion?
|
Filtered load = Filtered load * P
Excretion Rate= V * U Filtered > Excreted → substance is being reabsorbed Filtered < Excreted → substance is being secreted |
|
At what plasma level of glucose does glucosuria begin?
|
200 mg/dL
|
|
At what glucose plasma level are glucose transporters fully saturated?
|
375 mg/dL
