A 40-year-old member asked:

Find the cause: Level itself doesn't matter. It's a warning of possible underlying disease. You can raise your ALT very high just from a boozy weekend, while even a low ALT elevation may be the subtle clue that alerts your physician to hemochromatosis or Wilson's -- easy to treat, if detected, fatal if missed.

A 23-year-old female asked:

What is the normal range of ALT in the blood ?

Units per liter: The top of the reference range is set at around 40 u/l for most labs, but this should not be confused with a 'healthy range'. Most folks are well-below, and ethnicity and heredity may affect what is right for a person. The key is to know what to do with a number. The higher a person is above reference range, the more worrisome.

Hard to say: One Lab result alone doesn't mean much. It depends on why the test was taken and your symptoms and the results of other lab work. An abnormal lab can be a temporary finding and may be normal when next tested. Discuss this with your doctor (or the person who ordered the test), if if is concerning, you will be told and a plan to follow it up will be done (Ideally).
