What is the normal range for ALT and AST liver function values?

The correct normal range for alanine aminotransferase (ALT) and aspartate aminotransferase (AST) liver function values typically falls between 10-40 U/L for both enzymes in most laboratories. These enzymes are important markers for liver function and overall hepatocellular health.

When the ALT and AST levels are within this range, it generally indicates that there is no significant liver damage or disease. It's crucial to note that these values can vary slightly depending on the laboratory's specific reference ranges and the population group being tested. Therefore, knowing that a normal ALT and AST level is usually cited within this range is essential for interpreting liver function tests accurately.

Understanding abnormal values is also an essential part of clinical evaluation, as elevated liver enzyme levels can indicate liver inflammation, injury, or disease, necessitating further investigation and management.
