The ultrasound is a reasonable next step. You can also consider autoimmune hepatitis with a positive ANA as well as checking blood tests for viral hepatitis as well as a
ferritin level (looking for hemochromatosis).
If the ultrasounds is negative, a liver biopsy is recommended with an ALT of 390.
Further testing can be done based on the ultrasound results. For instance, if there is evidence of dilation, an MRCP or ERCP can be considered to look at the biliary ducts.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
