Part Descriptions

LP15333-5   Alanine aminotransferase
Alanine transaminase or ALT is an enzyme (EC also called serum glutamic pyruvic transaminase (SGPT) or alanine aminotransferase (ALAT). It is found in serum and in various bodily tissues, but is most commonly associated with the liver. It catalyzes the two parts of the alanine cycle. It is commonly measured clinically as a part of a diagnostic evaluation of liver health. Significantly elevated levels of ALT often suggest the existence of other medical problems such as viral hepatitis, diabetes, congestive heart failure, bile duct problems, infectious mononucleosis, or myopathy. However, elevated levels of ALT do not automatically mean that medical problems exist. Fluctuation of ALT levels is normal over the course of the day, and ALT levels can also increase in response to strenuous physical exercise.

LP15333-5   Alanine aminotransferase
Alanine aminotransferase (ALT) is an enzyme produced primarily in the liver but are also found in the heart, skeletal muscles, pancreas and kidney cells. The main function of ALT is to convert alanine into pyruvate. ALT is released into the bloodstream when cells containing it are damaged. Increased levels of ALT in the blood provide an early indicator of liver damage. ALT is often measured with aspartate aminotransferase (AST) as part of a liver panel. High levels of ALT could indicate hepatitis, obstructed bile ducts, liver tumors, cirrhosis, alcoholism or other liver disorders.

LP31991-0   Aspartate aminotransferase
Aspartate aminotransferase (AST) is an enzyme that is released by injured muscle cells and liver cell and is predominately found in the liver and heart. AST levels in the blood are most often used to monitor liver damage. AST is typically tested in conjunction with alanine aminotransferase (ALT) when a liver panel is ordered. High levels of AST in the bloodstream could indicate hepatitis, drug damage to the liver, cirrhosis, alcoholism, or other liver disorders. [Lab Tests Online:ast/tab/test] Source: Regenstrief LOINC
