Low levels of AST in the blood are expected and are normal. Very high levels of AST (more than 10 times normal) are usually due to acute hepatitis, sometimes due to a viral infection. In most types of liver disease, the ALT level is higher than AST and the AST/ALT ratio will be low (less than 1).

Why would AST SGOT be low?

AST formerly was called serum glutamic oxaloacetic transaminase (SGOT). Low levels of AST are normally found in the blood. When body tissue or an organ such as the heart or liver is diseased or damaged, additional AST is released into the bloodstream. Both ALT and AST levels can test for liver damage.

What does it mean if your ALT SGPT is low?

Your body uses ALT to break down food into energy. Normally, ALT levels in the blood are low. If your liver is damaged, it will release more ALT into your blood and levels will rise. (ALT used to be called serum glutamic-pyruvic transaminase, or SGPT). Doctors often give the ALT test along with other liver tests.
