ALT (SGPT)-254

Test info

84460.0
  
ALT
  
Alanine aminotransferase
SGPT
  

Markedly high levels of ALT may be found in a variety of diseases that involve the liver, such as hepatitis, mononucleosis, and cirrhosis. Because these very high levels are not seen in other disease processes, such as myocardial infarction, ALT is regarded as a reasonably specific indicator of Liver disease.

ALT (Alanine Aminotransferase), also known as GPT (Glutamate Pyruvate Transaminase), is one of a group of enzymes which catalyzes the conversion of amino acids and α-oxo-acids by transfer of amino groups. Transaminases are widely distributed in body tissues with significant amounts found in the kidney and liver. Lesser amounts are also found in skeletal muscles, heart, pancreas, spleen, and lungs. Injury, or disease processes, to these tissues results in the release of the ALT enzyme to the general circulation.
