Alanine Aminotransferase (ALT) (SGPT) (GPT)
(Liver Function) Blood Test
The ALT level is tested to look for and evaluate damage to the liver. This test measures the amount of an enzyme called glutamate pyruvate transaminase (GPT) in your blood. This enzyme is found in many body tissues in small amounts, but it is very concentrated in the liver. It is released into the blood when cells that contain it are damaged.
A liver function test, ALT is more sensitive for the detection of hepatocyte injury than for biliary obstruction. ALT is more specific for liver injury than AST (SGOT). Useful for hepatic cirrhosis, other liver disease. Increased in Reye syndrome, with AST.1 Test for hepatitis. Acute hepatitis A or B can be confirmed serologically, as can hepatitis C. Negative serological findings in the presence of hepatitis-like chemistry abnormalities may also suggest acute drug-induced hepatitis, an impression supported by resolution after removal of the offending agent.2 The combination of increased AST and ALT with negative hepatitis markers occurs in a number of other entities including infectious mononucleosis. Sensitive to heart failure.
Significant deviations from the normal range may require further evaluation for liver disease, more tests, diagnosis by your physician, in addition to Private MD’s recommendations.
