Is there anything else I need to know about an AST blood test?Your health care provider may order an ALT blood test along with your AST blood test. ALT stands for alanine aminotransferase, which is another type of liver enzyme. If you have high levels of AST and/or ALT, it may mean that you have some type of liver damage. You may also have an AST test part of a series of liver function tests. In addition to AST and ALT, liver function tests measure other enzymes, proteins, and substances in the liver.
