We are going through the same thing with Logan... Elevated liver enzymes since October. Had an ultrasound of his Gall Bladder and Liver in January that came back normal. His blood was retested on Feb 10th, his AST was 197 and ALT was 505 so they ordered a biopsy. He just had the liver biopsy on Thursday and when they drew the blood that day his AST was 354 and ALT was 907 <img src="i/expressions/face-icon-small-sad.gif" border="0"> His GGT has always been normal. Not sure what is going on yet and why his numbers are increasing so much
