I would get a full physical if you have not had one in the past year. That way you get ALL your bases covered and you might as well since you are there. Plus if you have a decent insurance they will cover most of the costs. Within the full physical you'll also be able to get your blood work done while fasted so you'll have more precise numbers to go by. The regular physical will cover your normal blood work like HDL/LDL, red/white blood cell count, hemoglobin, blah blah you get the point. You should then also ask for a full hormone panel. Your primary care doctor may not know the full range of hormones to test and may also not decide to pull those blood samples for you and may refer you to an endocrinologist which I would suggest as they would have a far better understanding and could give you a more comprehensive set of tests.
