Worried about the blood collection tube

[worrieradsadsa]

Hello! I had blood draw in hospital. I did not see if the blood collection tube was new or reused.

What I worried is if the blood collection tube is reused, contained the blood of the person before me.

Is it possible for the blood flow into my vein, then I get infected? I read some website said it is possible because of the pressure changed when the tourniquet is removed.

-hiv dont live outside the body on any surface for long time (cant be infectious)
-most of the needles used in lab are designed to be used for single use only, it cant draw blood more than once

Not possible at all because those tubes are specifically designed to pull the blood OUT. Think about it, if it was able to push blood back in, that would totally defeat the purpose for what it was meant to do. It would be useless for collecting blood in that case!
