It is possible that the stones is raising the liver enzymes. It would be helpful to know if the other liver enzymes and bilirubin as elevated as well. If it has been determined that the gallbladder is the cause, a surgery consult should be obtained to see if it needs to be removed.
From the information you provided, I cannot say for sure if this is gallbladder or liver.
Other labs to consider would be the rest of the liver function tests, including AST, GGT, total and direct bilirubin. There is a cancer marker test for liver cancer (known as the AFP), but this is not a screening test.
AMA is a test looking for primary biliary cirrhosis. This can be considered of all the other tests are negative. With the ultrasound findings, I would look at resolving that first, and then proceeding to other tests (i.e. a biopsy) if the treatment does not help the test findings.
Followup with your personal physician is essential.
