New Alcohol Markers—How Useful Are They in Population Studies: The Svalbard Study 1988–89
Regular high consumption of alcohol in selected populations have, with high precision, been identified by two new alcohol markers: carbohydrate‐deficient transferrin and mitochondrial aspartate aminotransferase. To test these markers in an unselected population, gamma‐glutamyltransferase (GGT), carb...
