What does it mean when AST and ALT are elevated to 1.7 μ/L?

Under normal circumstances, "AST" and "ALT" refer to aspartate aminotransferase and alanine aminotransferase, respectively—two common liver function markers in the blood. A ratio of aspartate aminotransferase to alanine aminotransferase of 1.7 μ/L is considered mildly elevated and requires comprehensive evaluation of liver health based on clinical symptoms and other liver function tests. The detailed analysis is as follows:

AST and ALT are two enzymes measured in liver function tests. Aspartate aminotransferase (AST) is also known as serum glutamic-oxaloacetic transaminase, while alanine aminotransferase (ALT) is also called serum glutamic-pyruvic transaminase. Normally, the reference ranges for these two enzymes are ALT ≤ 40 U/L and AST ≤ 37 U/L. When the AST/ALT ratio exceeds the normal range, it typically indicates liver damage or the presence of other diseases such as hepatitis B or C, fatty liver disease, or cirrhosis. A value of 1.7 is mildly elevated and should be evaluated together with clinical symptoms and additional liver function indicators. It is recommended to seek medical attention promptly and follow the doctor's advice for treatment.

If elevated levels are detected, timely medical consultation is advised to avoid delaying diagnosis and treatment. In daily life, it is important to maintain healthy habits and avoid consuming spicy or irritating foods, which may hinder recovery.
