Why Alt Is High?

When your liver is damaged or inflamed, it can release ALT into your bloodstream. This causes your ALT levels to rise. A high ALT level can indicate a liver problem, which is why doctors often use an ALT test when diagnosing liver conditions.

What causes ALT to be high?

High levels of ALT can be a result of damage or injury to cells. Because ALT is most concentrated in the liver, abnormal ALT test results are generally associated with conditions affecting the liver, such as inflammation (hepatitis) and scarring (cirrhosis).

What is considered a high ALT level?

The upper limit of normal for ALT is 55 IU/L. When an ALT level is double to triple the upper limit of normal, it is considered mildly elevated. Severely elevated ALT levels found In liver disease are often 50 times the upper limit of normal.
