The AST/ALT ratio or De Ritis ratio is the ratio between the concentrations of the enzymes aspartate transaminase (AST) and alanine transaminase, aka alanine aminotransferase (ALT) in the blood of a human or animal. It is measured with a blood test and is sometimes useful in medical diagnosis for elevated transaminases to differentiate between causes of liver damage, or hepatotoxicity. Most causes of liver cell injury are associated with a greater increase in ALT than AST; however… Web21 de jun. de 2024 · AST tends to rise with ALT if liver damage is present. Alkaline Phosphatase (or ALP for short): ALP is produced by the cells lining the bile ducts or the “plumbing” of the liver. A rise in ALT is commonly seen in conditions that caused blocked “ducts” such as bile stones or direct damage to the bile ducts.
