Elevated ALT and AST levels within the lab's normal range can indicate liver inflammation or scarring.

“now liver function test is a bit of a misnomer here these are enzymes that are produced by the liver under the stress of the liver so as the liver is experiencing any inflammation or scarring these numbers will get higher and higher and higher and we think of normal as generally below 20 but the lab says normal is below 40. we've had this discussion at length bob i'm pretty sure and i know i think rob lustig actually discussed this on one of the episodes as well so 32 and 32 is acceptable but that's interesting okay it's not perfect”
