The kidneys are the major regulators of the water, electrolyte, and acid-base content of the blood and, indirectly, all body fluids. This is accomplished through filtration, reabsorption, and secretion. Kidney function test is key in ruling out diseases of the kidneys such as infection (pyelonephritis), stone formation (nephrolithiasis), dilation (hydronephrosis), protein loss (nephrosis), cancer (hypernephroma), and acute or chronic renal failure.
