Had my 6 month bloodwork drawn this morning. I ended up passing out. I warned the tech that I get seriously dizzy and lightheaded after a few vials so they were ready for it. That was not a fun an experience.
I have to say, they take 13 vials from me. I am guessing it is similar for most of us. I dont normally get dizzy when giving blood but i can definately tell the difference after getting my nutritional panel tested.
I fully expected to get woozy, but never expected to actually pass out. In the future I'm going to have to see if I can do the draw over two visits because I am not going through that again.
