Is it normal to have increased levels of ALT and AST after getting flu shots?

I recently had a flu shot. The next day, I had some routine blood work done. This evening my Doctor s office informed me that my AST and ALT levels were heightened. One was 47 (normal 10 - 30) and the other was around 60 (normal 6 - 40). Could the flu shot cause these heightened levels? Thanks, Annette

You have not mentioned the name of medications, dosage, and your personal information.

As a result, I can't say whether it is related to Flu shot, but the good point is your liver enzymes (ALT and AST) is not elevated more than 3 times than the upper limit of normal, so I would suggest you wait for 2 weeks after that you can retest your liver enzymes.

Hope I have answered your query. Let me know if I can assist you further.

Take care
