Abstract
Conventional laboratory tests: gamma glutamyltransferase (GGT), alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT), mean corpuscular volume (MCV), cholesterol, and high-density lipoprotein cholesterol (HDL-cholesterol) were studied as possible markers of heavy drinking in a sample of 1,619 first-year university students in Helsinki. Alcohol consumption was measured on a frequency-volume scale. No significant (p < 0.001) correlation between the laboratory tests and reported drinking was found. However, significant differences between different drinking groups were found in GGT, MCV, and HDL-cholesterol in both female and male students and in cholesterol in male students. We conclude that, even if alcohol drinking has some impact on GGT, MCV, HDL-cholesterol, and cholesterol (males), these tests are neither specific nor sensitive enough to be used as screening tests for heavy drinking in young students.
