ALT (Alanine aminotransferase) and AST (Aspartate aminotransferase) levels are typically measured through a blood test. A small sample of blood is drawn from a vein, usually in the arm, and sent to a laboratory for analysis. The blood test measures the amount of these liver enzymes present in the blood. The results can provide valuable information about liver function, potential liver damage, or specific liver conditions. It is important to consult with a healthcare professional who can interpret the results and provide appropriate guidance based on the individual's specific circumstances.
