Q
Renal clearance?
A
C = UV/P
2
Q
GFR?
A
Clearance of inulin or CrCl, or hydrostatic pressure - oncotic pressure
3
Q
Effective renal plasma flow?
A
ERPF = UV/P of PAH
4
Q
Renal blood flow?
A
RBF = RPF / (1 - Hct)
5
Q
Filtration fraction?
A
FF = GFR/RPF
6
Q
Filtered load (total filtration rate)?
A
Filtered load = GFR x plasma conc

Q
Excretion rate?
A
ER = U x V
