Eighty three patients with alcoholism were evaluated on several biochemical parameters against seventy five healthy controls. Linear discriminant analysis of three laboratory tests (GGT, GOT and GPT) yielded accurate diagnosis among 63% of the total sample. Sensitivity of these tests was 47% and specificity 80%. Repeat analysis of these three test among 50 alcoholics following thirty days of abstinence showed significant decline of values. Preliminary observation suggests improvement of liver function following cessation of drinking habit.
