Getting Blood Drawn??? Do I need an appointment???

Can I just go up to the hospital and go to the lab or do I have to make an appointment? I am terrified of getting it done because I pass out everytime and it feels like I am going to die before it happens but I really need to get them done tomorrow for my 6 week check up.

I assume most hospitals are all the same, but where I work, you can walk in as long as you have your order with you, no appointment is necessary.

Thanks.
