After age 40, GFR decreases progressively with age, by 0.4–1.2 mL/min per year. In children, GFR measured by inulin clearance is 110 mL/min/1.73 m 2 until 2 years of age in both sexes, and then it progressively decreases. The normal range of GFR, adjusted for body surface area, is 100–130 average 125 mL/min/1.73m 2 in men and 90–120 mL/min/1.73m 2 in women younger than the age of 40. Staging of chronic kidney disease is based on categories of GFR as well as albuminuria and cause of kidney disease.

Both GFR and C Cr may be accurately calculated by comparative measurements of substances in the blood and urine, or estimated by formulas using just a blood test result ( eGFR and eC Cr) The results of these tests are used to assess the excretory function of the kidneys. Creatinine clearance exceeds GFR due to creatinine secretion, which can be blocked by cimetidine. The creatinine clearance rate ( C Cr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Glomerular filtration rate describes the flow rate of filtered fluid through the kidney. One of the measures of kidney function is the glomerular filtration rate ( GFR). Renal functions include maintaining an acid–base balance regulating fluid balance regulating sodium, potassium, and other electrolytes clearing toxins absorption of glucose, amino acids, and other small molecules regulation of blood pressure production of various hormones, such as erythropoietin and activation of vitamin D. The basic physiologic mechanisms of handling fluid and electrolytes by the nephron - filtration, secretion, reabsorption, and excretion - are labelled.
