Method for diagnosing acute alcoholic hepatitis

A method for assessing a subject as having acute alcoholic hepatitis (AH) comprising:

• receiving an exhaled breath sample from a subject;
• determining the level of trimethylamine (TMA), the level of acetone, and the level of pentane in the exhaled breath sample obtained from the subject using an analytical device;
• determining a TAP score based on the concentration of trimethylamine, the concentration of acetone, and the concentration of pentane in the exhaled breath;
• and
• diagnosing the subject as having alcoholic hepatitis based on the TAP score.

A method of identifying a subject having acute alcoholic hepatitis (AH), comprising:

• receiving an exhaled breath sample from a subject;
• determining the level of trimethylamine (TMA) in the exhaled breath sample obtained from the subject using an analytic device;
• and
• diagnosing a subject as having alcoholic hepatitis if the exhaled breath sample contains a level of trimethylamine that ranges from about 14 ppb to about 40 ppb.
