From my experience as a medical professional, I really don’t think that would deter them from surgery. That is just a slight elevation. I’m sure your doctor will relay the same thing to you. Acetaminophen can be taken for short duration’s at 4000 mg per day. If you were taking other medication‘s that are processed through the liver that Hass to be taken into consideration as well. Also, if alcohol is consumed, that is processed through the liver. But overall I would not be that concerned with those numbers at this point. But they do deserve to be watched. I hope that was helpful and relieved some of your stress.
