Reference Range. Alanine aminotransferase (ALT) is an enzyme found primarily in the liver and kidney. It was originally referred to as serum glutamic pyruvic transaminase (SGPT). Normally, a low level of ALT exists in the serum.ALT is increased with liver damage and is used to screen for and/or monitor liver disease.Alanine aminotransferase (ALT) is usually measured concurrently with AST as part of a liver function panel to determine the source of organ damage.ormally, a low level of ALT exists in the serum.
