I want to know about titers and heptatits B shots

I have to get my titers and heptatits B shots before I can start my program.

Can someone tell me how titers are done? And what happens during heptatits B shots? Will I get a shot in the upper arm area??
Your titers are done by a simple blood draw.

The Hep B is a series of three shots given in the upper arm. Not all that much to it. I got them done in elementary school.

where do they draw the blood from the hand or the arm?

On the arm, opposite of the elbow. You know the whole 'put the rubber thingy on your upper arm, find a vein, and stick' process. Not much to that either. Just a prick. You've probably had it done before at least one time when you've gone to the doc for a yearly physical.It can be done on the hand too, but I've never experienced it like that. Believe me, I've had at least 20 blood labs done in the last 2 years at three different facilities.

How long are Titers good for? are ones i got 2 years ago still good? or i gotta get em redone?

If you had positive titers 2 years ago there's no reason to think your immunity would decrease so I don't see why they'd need to be redone.
