I had elevated pancreatic enzyme levels at a doc visit a week ago. My ultrasound isn't until two weeks from now, will whatever is wrong still show up?

Maybe not. Are you symptomatic at this time, that may warrant a more expedient and aggressive evaluation?
Probably. Basically looking for pancreatitis or complications of pancreatitis. These abnormalities do not disappear quickly.Many tim es pancreas can still appear normal even with pancreatitis.Pancreatitis with severe pain may require hospitalization and fasting with intravenous therapy. Therapy depends on severity of inflammation.
