recently i had a vacuum blood draw in a regulated hospital in China.
i can't remember whether if the nurse changed the needle to perform the blood draw on me.
and i think ,even if she DID reuse the needle, it wouldn't be a risk, here are my reasons. please let me know if i m wrong or not.
1-the blood would be flowing only outward, not inward. due to the pressure from the vacuum tube.
2-the tiny blood on/around the needle point wouldn't be enough to be infectious.
3-i think there was a time gap between me and the previous one who had a blood draw, maybe around 10 minutes or so.
i am still worried about it, please let me know if i m right or wrong. thank you all very much
