Very high liver markers out of nowhere

A blood test I took 3 weeks ago showed: AST: 179 ALT: 658 Ferritin: 467

Yes you read those numbers correctly.

I repeated the test a week ago and the numbers had halved, but are still in the red zone. I’m getting a liver ultrasound this weekend to see if it shows anything.

I’ve never had issues with these markers before, and they came out of nowhere. I’ve always been told I have a bit of a fatty liver but it was nothing to worry about. I don’t drink or eat bad, and haven’t changed anything in my lifestyle recently.

Had anyone ever experienced anything like this? I have no idea what could have caused it, and neither does my doctor.
