Hi there, My ggt was 111 due to over drinking while on holidays and a few social events. I was wanting to know how long it usually takes before can re re test my results? I have stopped drinking for 12 days now, my other results were all normal except alt of 53. I m 6 foot 2 - 85kg and 37 years old. I keep very fit and exercise at least 5 days per week. Non smokers. Thanks James.
