The ALT blood test measures the level of the enzyme alanine transaminase (ALT) in the blood. ALT is found primarily in the liver, but is also found in smaller amounts in the kidneys, heart, muscles, and pancreas. The ALT test checks how well your liver is working and evaluates its overall health. The ALT test was formerly called serum glutamic pyruvic transaminase (SGPT). ALT is typically measured to determine if the liver is damaged or diseased. If the liver is damaged or diseased, it will release ALT into the blood.
