My apology. GGT is not as specific a liver marker as ALT.

"However, unlike ALT, GGT was also associated with blood pressure and smoking. In 2011–12, people with high blood pressure were more likely to have abnormal GGT than people with normal blood pressure (20.2% compared to 10.3%). Similarly, 18.1% of current smokers had abnormal GGT compared with only 9.6% of people who had never smoked."

Thanks u for your comment.im am asking about GGT level not alt.have u any information about the relation between it and smoking

We don't know of any direct relationship between smoking and ALT. Long term smoking is bad for the health and will worsen the effect of a chronic HBV infection and greatly increase the risk of cancer. ALT for male should be under 30 iu/l (19 iu/l for female). ALT can fluctuate between morning and evening, so it is a pattern of consistent normal ALT that is important.
