I found myself returning after I thought I was assured with my results after 4 months of my virtually no risk incident. I started worrying about the needle used during that test. I didn’t see the nurse removing the needle from new bag so I thought it was reused and the spiral started all over again. She used a butterfly needle and I saw the cap was on and there was no trace of blood inside the tube but what drove me nuts was I don’t recall seeing her remove the needle from a new package. It’s been exactly 45 days since that blood draw concern and I’m thinking to test again to put all these worried to rest. 

What do you think Dr? And do you think the butterfly needle can’t be technically reused as it is tiny and the previous patient blood will clot inside which will make it hard to suck my blood? And if it was used before I keep sayin I could easily see the remains of previous blood in the tube!

I look forward to your usual timely and satisfying answer.

As for this particular event, HIV is never transmitted by having blood drawn:  it used to happen rarely, before HIV was discovered as the cause of AIDS, over 40 years ago -- at a time when some health care providers re-used needles, syringes, etc. without proper sterilization between patients. That never happens anymore, and your concerns are entirely unfounded. And as you suggest, blood draw equipment now is designed to prevent re-use -- and why would anybody want to re-use the equipment anyway? In the last 30-40 years, probably nobody in the world is known to have acquired HIV or other blood borne infections (e.g. hepatitis B or C) because of how blood was drawn. There is no possibility of that from the scenario you describe and no need to be retested for HIV.

Newer update, between me asking the question and you answering, I found myself rushed to the lab to take the 45 day mark test (4th gen lab test) and the result just came out Negative… what a relief! Is it now conclusive? 

Medically and psychologically, you advise me not to even give it more thought and the result proves even that shadow of doubt in my mind is unwarranted… no more testing.. right? 

Dr. you wouldn’t believe the paranoia I have been living in for the past months.

Of course I "believe" your paranoia. It was advertised in bright red flags in your question, and to some extent in your previous threads. This is going to have to be your last about HIV concerns from potential exposures that are well known to be nonsensical. If and when you have a true high risk event (like vaginal or anal sex with a high risk partner), feel free to ask us about it. But no more about the sort of nonsense asked about here (which intellectually you probably know IS nonsense). The forum does not permit repeated questions on the same topic or exposure. This being your third about obviously zero risk events, it will have to be your last; future new questions along these lines may be deleted without reply and without refund of the posting fee. This policy is based on compassion, not criticism, and is designed to reduce temptations to keep paying for questions with obvious answers; because experience shows that continued answers tend to prolong users' anxieties; and because such questions have little educational value for other users, one of the forum's main purposes. Thanks for understanding. I do hope the discussions have helped you; best wishes and stay safe.
