here in China they draw my blood and they use a new needle that penetrate my skin, and i did not see the nurse use a new blood transfer
device that has another needle in it that screws the
vacuum container, and they use the same collection to draw two blood, so they draw the first one then they stop and get the other vacuum and put it in the same needle, what worries me is that the nurse maybe did not use a new blood transfer device that it has it own needle am i at risk?
