Blood stain on drawing blood chair, very worried!

Question: 

The blood stain was red-orengeish and small. I put my right arm on it. It was on a tissue covering the right arm of the chair. I told the nurse to draw the blood from my other arm, the left one. Afterwards I washed my right arm with a lot of soap.

But now I am worrying that the nurse could have touched that stain with the needle or with her hands. I didn't see her touch it but I keep obsessing over this.

What do you think?

I don’t know how to explain it, but the stain didn’t leave any mark of blood if you touched it. The tissue had completely soaked that tiny amount of blood. There was no trace of blood on my arm when I washed it.

Do I need to get tested? I don't engage in any risky behaviour, so, except for this episode, I am not at risk. if I wanted to be tested, how long should I wait? The blood drawing happened today.

In the hypothetical case that the nurse had touched the stain with the needle, would I be at risk?

Answer: 

Hello,

Thank you for your inquiry. From from what we gather from the question, you are asking about the risk of HIV acquisition from a bloodstain on a chair.

From the information given, this scenario is determined to be no risk (transmission of HIV is not possible in the given scenario), because the blood has been exposed to oxygen and there is no direct access to the bloodstream. HIV is rendered inactive by exposure to oxygen, and requires sealed, air-tight access to the bloodstream in order for transmission to take place.
