I have seen a few ppl asking how long it takes for CDT to return to normal so have posted biomarkers on the table below.
Marker | Time to return to normal limits | Type of drinking characterized | Comments |
---|---|---|---|
Gamma–glutamyltransferase | 2–6 weeks of abstinence | ∼ 70 drinks/wk for several weeks | Many sources of false positives |
Aspartate aminotransferase | 7 days, but considerable variability in declines with abstinence | Unknown, but heavy | Many sources of false positives |
Alanine aminotransferase | Unknown | Unknown, but heavy | Many sources of false positives Less sensitive than aspartate aminotransferase |
Macrocytic volume | Unknown but half–life ∼ 40 days | Unknown, but heavy | Slow return to normal limits even with abstinence |
Carbohydrate–deficient transferrin | 2–4 weeks of abstinence | 60+ g/d for at least 2 weeks | Rare false positives Good indicator of relapse |
