etc. I asked the lab nurse to make sure that everything is new and disposable. She said yes and the old injections are thrown in a special box that she touched in front of me. After she took my blood I went and looked at the side of the trash she touched and there were blood stains (when they throw the used syrnges some of the blood drips on the side) so for sure she touched the blood and touched me. Not sure how old is the blood. Is there any risk please advice and it's my last question.
