The health care provider will perform a physical exam and ask questions about your medical and family history, including use of alcohol.

The following questions are used by the National Institute on Alcohol Abuse and Alcoholism to screen for alcohol abuse or dependence:

• Do you ever drive when you have been drinking?
• Do you have to drink more than before to get drunk or feel the desired effect?
• Have you felt that you should cut down on your drinking?
• Have you ever had any blackouts after drinking?
• Have you ever missed work or lost a job because of drinking?
• Is someone in your family worried about your drinking?

Tests that may be done include:

• Blood alcohol level (this can tell whether someone has recently been drinking alcohol, but it does not necessarily confirm alcoholism)
• Complete blood count (CBC)
• Liver function tests
• Magnesium blood test
