Simple blood test.....not quite so simple nor reliable... pacificlife.com " HAA (hemoglobin associated acetaldehyde) was the first to be widely used, and CDT (carbohydrate deficient transferrin) became an FDA approved test to detect chronic alcoholism. While CDT is reasonably accurate to detect those who drink considerably (5 or more drinks a day for a week, or 50-80 grams of alcohol over a two week period), it is not perfect. The specificity of the test is about 85%- just at the realm of acceptability, but the sensitivity is a less reliable 50%. A negative CDT does not rule out a problem drinker, in that less than the stated limit of alcohol use can be quite dangerous to many people. Likewise, CDT generally normalizes within 10-14 days after alcohol intake is stopped, so it may miss binge drinking. Generally though, binge drinking does not elevate CDT, and there are few biological conditions that cause a CDT to be elevated for a non-alcohol related reason."
