Hello All,

I had gone to draw blood at a lab for routine checkup. The guy who was drawing blood use a new needle and holder but by mistake he used an old vacutainer tube which had blood on it from previous patient. As soon as he saw that, he freaked out and I called the manager immediately but it was already late . I think the guy was stoned or high or whatever. And I am going crazy because of this.

Am I at risk of any blood disease? especially HIV?

When do I test?

Please help me

No the tube doesn't always use its vacuum. It only loses its vacuum if they take it out of the arm when the tube is pressed into the rubber gasket that is inside the vacutainer.  It is a particular mechanism. But even if it didn't have its vacuum it wouldn't go back into your vein. So no problem there either. It isn't  like an IV or injection that  a doctor or nurse gives you.

Okay thanks Just a query,I was going through forums, and I learnt that once the tube is punctured, it looses it's vacuum and thus no blood can be drawn. Now, as there was no vacuum in the tube, can the blood from the tube flow into the vein because of negative pressure?
