What do low AST 13 (15-37 U/L range) and ALT 34 (30-65U/L) normal, but low side) mean?

As well as having LOW Potassium is 2.8 (3.5-5.1) mEq/L and total brillium was 0.3 (0.2-1.0mg/dL) and MHCH was High at 35.5 (30.9-33.8 g/dL) all at the same time, OH and they released me absolutely feeling like crap I have to say, with having no one at home.
