Normal range on Quest diagnostics is 9 - 60.
If you drink a lot of alcohol quitting may improve your ALT. If it is due to something else - hepatitis c or b, for example, you may need to take medication.
Regardless, you should see a doctor, preferably a gastroenterologist or a hepatologist, who can order blood tests to determine what is causing your enzyme elevation. ALT is a liver enzyme and when it is elevated it reflects the fact that liver cells are dying at a higher than normal rate. The higher the ALT the higher the cell death. 158 is not extremely high, by any means, but it is high enough to warrant further testing.
I just had a blood test come back with ALT levels at 8000! I am otherwise a healthy 33 year old who exercises moderately. Could this elevation be from the muscle break down instead of the liver?
