what is normal range for alt/sgpt test
I just found this at Medicine net. The normal range of values for AST (SGOT) is from 5 to 40 units per liter of serum (the liquid part of the blood). The normal range of values for ALT (SGPT) is from 7 to 56 units per liter of serum. Those aren't the same as Quest but they're in the ball park. I know different labs have different reference range but an AST range of of 14 - 20 seems very narrow.
