Hello doctor, I am in very tensed situation as I went yesterday for routine blood test. The blood drawn was done by vacutainer. The syringe was new and the tube was also new but the holder was reused. And after taking blood I saw the person cleaning my blood from the mouth of holder. This scared me a lot as mine blood was there it might be possible that some other patient blood would be there who would be tested before me. I searched the internet and I scared more as reading that it might contract hiv, hep B and C. Sir what should I do now. Do I require testing for hiv? Is my fear real or it is only anxiety? Sir please answer asap.
