These tests are performed on blood samples, and most measure the levels of enzymes or other substances in the blood. Depending on the type of disease or injury suspected, doctors may also order imaging and scanning tests or take a sample of liver tissue for a biopsy.
Albumin is a water-soluble protein made by the liver that is one of the main constituents of blood.
Serum proteins are also made in the liver. Albumin and serum protein are important in maintaining correct pressure between the fluids of the vascular system and surrounding cells. They also are important in transporting chemicals, including some medications, throughout the blood system. The measurement of these proteins is a rather insensitive indication of kidney or gastrointestinal tract function. An enzyme called serum glutamate pyruvate transaminase is normally found in high concentrations within the liver.
