AST-276, 109 : 15-41 is the ref range I have, so that looks very high
to me. I have an old lab book called A Manual of Laboratory Diagnostic Tests. It's a second edition by Frances Fischbach. It says, " AST is an enzyme present in tissues of high
metabolic activity." "The enzyme is released into the circulaton following the injury or death of cells. Any disease that causes change in these high
ly metabolic tissues will result in a rise in AST.
