I Am Not A Big Drinker At All. However I

I am not a big drinker at all. However I drank a red plastic of whiskey 2 days before I had bloodwork...and my liver levels were elevated. At the time when the doctor asked me upon getting the results if I drink I said no, as I forgot since I do rarely drink (EAGLES first preseason gm smh) Do you think this caused my levels to jump?
