I had a GGT test and just got the results. My ALT was 10 (normal is 6 - 40), AST was 15 (normal is 10 - 30) Bilirubin is .4 (normal is .0 - 1.2) but my GGT was 100 (normal is 3 - 50). I drink alcohol when I come home from work but does this test mean I have liver damage and need to stop drinking all together? I want to know basically, what this means? My Endocrinologist had no idea what the test meant because she never does it but I put it down for my blood test cause I was watching Dr. OZ and thought I should. I"m a a little scared and I'm 38.
