Has anyone had a blood test and no blood came out?

Hi all, I've had some blood tests done yesterday at hospital and the nurse found it very hard to get blood out of me even though she put the needle in my arm properly. I was wondering if this has happen to anyone before?

I do have a heart condition and very low blood presser.

last yrar went to the ER after my knee replacement surgery a nonth or so later.

they could get nothing out for a sample, they had to put a port in.

forgot to tell you the RN came in to take my blood "Passed Out",

she was cute!! skyradde/darryl

Sometimes if your vein collapses you can't get blood out of it.
