ALT (Alanine Transaminase) the new “normal”

ALT is an enzyme found mainly in the liver that helps the liver metabolise food into energy. Elevated levels of ALT in the blood can occur when the liver is damaged or diseased.

ALT levels are a poor predictor of non-alcoholic fatty liver disease (NAFLD) but is often elevated.

ALT is can be considered a biomarker or surrogate marker for degree of liver fat.
