In recovering alcoholics, GGT is a very sensitive measure of alcohol consumption and will almost certainly be elevated if he relapsed 1 week ago. It may be elevated in up to 20% of recovering alcoholics who have not relapsed though, so the result may be high in a few people who have remained abstinent.
MCV is a bit different and is more a measure of the vitamin deficiencies associated with chronic alcoholism. I'm not sure that this would be high if he just relapsed 1 week ago.
