Blood work

I received my lab orders for all sorts of blood panels and just had it done yesterday....soooo much blood taken! I had no idea! The lady at the lab was like, don't worry, the first one is the biggest and then the subsequent orders are less.

They said the office would have the results today, will they contact me if there is something wrong? Or is this something they will go over during my first appt next week? Just not sure what I should be doing. This is all so new and confusing sometimes.
