Renal function affects many areas of health, disease and medicine and is itself affected by many. The term renal function often refers to acid-base/electrolyte/water homeostasis and excretion. However, the kidney is also intimately involved in erythropoiesis and vitamin D metabolism (and some other metabolic processes).

Determining the patient's renal function in order to descide on treatment or action is a common, less than perfectly simple, activity.

Measurement of renal function in clinical practice

Various methods of measuring as well as estimating glomerular filtration rate exist[1]. Creatinine clearance may be measured.

Estimation of renal function in clinical practice

An estimated glomerular filtration rate can be derived by various formulae.
