GGT can help add context when ALP is high and may help clinicians decide whether a pattern looks more liver-related.
Yes. Some medicines and supplements may be associated with higher GGT, which is why clinicians review medication history.
No. Alcohol is one possible factor, but several liver and bile-duct patterns may also affect GGT.
