Hi, I would google it. I think it has a lot to do with your liver. I know mine was slightly high
a few yrs ago, 3.5 labs range was 2.6 to 3.2. I know I looked it up and your total protein is important as well as albulin.
I would ask your Dr. to do a break down, mine wouldn't because he said it wasn't off by much!!
Like it was ganna hurt him!!
Let us know what you find out.
Good luck..........georgie
