Define and explain differences between ERPF and GFR calculations
Effective renal plasma flow (eRPF) is a measure used in renal physiology[1] to calculate renal plasma flow (RPF) and hence estimate renal function.
Glomerular filtration rate (GFR) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood.
GFR is inversely proportional to the renal plasma flow! The GFR is used to estimate kidney function and to stage chronic kidney disease.
