Hello my doctor asked me to retake a blood test to test my ALT levels in a month. I had been drinking about three days before I took the blood test so I was wondering if that would have resulted in high ALT reading and that is why asking for me to do a retest? How much damaged must your liver for you to have a high Alt reading? Thank you
Hi Bib. You didn't mention how high ALT is. 2x or 3x higher than normal is a sign of hepatic or biliary damage usually biliary obstruction or gallbladder stones) It can be caused by alcohol or any other factor. More specific test for alcohol abuse is GGT. If only ALT is raised, and you consider that you are not heavy Chat Doctor.  Ultrasound can visualize is there any sign of cirrhosis. You should do frequent liver enzyme test and stop
