I had a blood test conducted on Saturday however I was drinking fairly heavily on Friday night.  I was unaware my doctor was going to want to take blood on Saturday which is why I didnt refrain from drinking.  My AST level was 69 and my ALT level 88.  My doc wants to re test; but could this be from drinking heavily the night before the test?
Hi and welcome to Chat Doctor.AST and ALT are unlikely to get so fast elevated after drinking. It would more likely be GGT so is elevation can be caused by chronic frequent Chat Doctor.  These are mildly elevated enzymes and there is still no reason to worry. Other causes are viral, autoimmune or toxic liver damage. The most common liver disorders are fatty liver which can be found in healthy people, but usually is resulting from elevated blood lipids, overweight and elevated blood sugar. If ultrasounds didn't find anything and viral markers are negative then you have no reason to be concerned. You should treat it by changing dietary and lifestyle habits. Do exercise, avoid alcohol, smoking, fats, fast food and carbonated
