Ask your doctor. Not all blood tests test the liver but when you know that a test has been done, ask. One of the things they look for is to see if the key unit being measured is 62. That is the magic number. An alcoholic or drug user can measure as high as 1,500 units...when they do, they are about months from needing a liver transplant. Since liver function is so related to what goes into the body, it is good to know if your number exceeds 62 from medications or addictive substances, or pollution. Good luck.
