<s>[INST] Hi,Recently i had a random blood test and i found that my ggt level is 188 ! While other liver function tests were normal . I had an ultrasound which showed smooth liver surface, clear biliary flow and normal sized kidneys and liver .. I ve heard that ggt levels become high in relation to alcohol intake but , i have never drank alcohol ! So i was wondering if you can give me any ideas about the reason behind this elevated level ?? Thank you in advance .. [/INST] Hi, GTT is found in many parts of the body, including the kidneys, liver, pancreas, intestine, spleen, heart, brain, etc. So GGT alone is nonspecific Increased GGT levels can be seen in many conditions--many liver diseases, Pancreatitis, many cancers, Alcoholism, heart diseases. GGT levels may be increased due to medications also.  Smoking may also cause elevated GGT levels. So, if you have no other investigation suggestive of any diseases, no need to worry. Do not run after a single investigation which is non-specific. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  Rammstein, General Surgeon </s>
