Alanine transaminase (ALT). ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. When the liver is damaged, ALT is released into the bloodstream and levels increase. This test is sometimes referred to as SGPT. Aspartate transaminase (AST). AST is an enzyme

27 lut 2024 · An increase in both AST and ALT serum levels is common. ALT levels greater than 1000 U/L should be considered acute ischemic liver injury, severe drug-induced liver injury, or acute viral hepatitis. Other causes include common bile duct stones and hepatitis E infection.
Elevated AST and ALT levels may indicate liver injury. These are the enzymes that are most commonly released into your bloodstream when your liver is stressed. If both are elevated equally, it indicates a nonalcoholic type of injury, which may include infection or other toxins.
