what is normal for liver test
Liver blood tests are designed to show evidence that abnormalities, for example, inflammation, liver cell damage, has or is occurring within the liver. The blood tests most frequently used for liver disease are the aminotransferases (alanine aminotransferase or ALT and aspartate aminotransferase or AST). Normal levels of ALT ranges from about 7-56 units/liter, and 10-40units/liters for AST. Elevated levels of AST and ALT may signify the level of liver damage in a person.
