An alcohol test is not a singular test. By the time your doctor suggests that you should get an alcoholism test done, or by the time you yourself realize that you need to get an alcoholism test, you may already realize that alcoholism has become a problem for you. Now you need to find out what damage alcohol has done to your various organs. So, you may need a liver test, a kidney test, a lipid profile test, a diabetes test and an array of other tests to assess the damage and then take corrective measures.
