What is the normal range for the transaminase ratio?

1. The ratio of transaminase mainly refers to the ratio of alanine aminotransferase (ALT) to aspartate aminotransferase (AST). A transaminase ratio of 0-40U/L is considered normal.

2. Transaminase can be divided into AST and ALT. Both are important indicators for detecting liver damage and myocardial damage, and they also have diagnostic significance for kidney damage and skeletal muscle abnormalities. The common cause of abnormal transaminase ratios is liver damage. Liver cells contain a large amount of transaminase, including ALT and AST, while the blood contains relatively little. When these cells are damaged due to inflammation, tumors, or other factors, cell necrosis occurs, increasing cell membrane permeability. This results in the release of ALT and AST from the cytoplasm or mitochondria into the blood, leading to an increase in blood test indicators and indicating related abnormalities.

3. Abnormal transaminase levels are commonly seen in fatty liver, alcoholic liver disease, drug-induced liver injury, viral hepatitis, hepatitis, liver cirrhosis, liver fibrosis, biliary stones, biliary infections, intrahepatic stones, etc. Hepatobiliary tumors may also cause abnormal transaminase levels. Additionally, causes such as myocarditis, myocardial infarction, nephritis, and abnormal skeletal muscle damage can also lead to abnormal transaminase levels. If transaminase levels are abnormal, further detailed testing is required.
