Had blood test my liver test came back at 68. i am over weight my doctor said it's nothing to be worked over. send me for more tests. i am nervous.

Should be concerned: This is probably your AST / SGOT and / or ALT / SGPT. If they're up, it's most likely your weight problem / lack of exercise which in genetically-predisposed people will do this. We need to rule out alcohol, meds, hepatitis B and C, hemochromatosis, Wilson's, and a few other treatable things that will kill you if missed. Best wishes.
