AST (aspartate aminotransferase; also called serum glutamicoxaloacetic transaminase; SGOT) – an enzyme that is made in many places throughout the body (heart, intestines, muscle) , which is monitored (as with ALT) routinely in HIV-positive people on ARVs to detect liver toxicity from HIV drugs (or other medications). Elevated AST that is specifically made in the liver signals liver injury, but does not indicate how serious liver damage is.
