Kidney And Liver Enzymes. The kidney function tests do not measure enzymes but measure breakdown products of normal body processes. As a result elevated amounts of alt and ast enzymes found within the bloodstream can be an indicator of liver injury.
Blood urea nitrogen bun is produced as a result of protein breakdown. During hepatic injury and liver cell death these enzymes are released into the bloodstream. Liver enzymes help us determine if there is damage to the cells of the liver or direct damage to the liver tissue itself.
When used comparatively ast and alt can help identify liver toxicity liver disease or liver damage.
1 the liver enzymes are made by the liver cells. Liver enzymes including alanine aminotransferase or alt and aspartate aminotransferase or ast are found within liver cells. Normally liver and kidney enzymes stay in the liver or kidney. In other organs also.
