I tried finding information from your other posts here but nothing this specific I have came across. 

I stood up the whole time to gather what was needed for work. I had to lean over on the kitchen table to sign off on a paper and noticed that the side of my hand, on top of the table, landed on something “crunchy” if that makes sense. Didn’t think much of it and just brushed it off. Then right after my mind started wondering. 

Could it have been broken glass from a used syringe? Could it have been a broken needle from a used syringe? (Meaning a tip of the syringe needle)

I did check the side of my hand. Noticed no blood. No puncture wound(which I assume would be obvious?). 

My questions:

1) would a broken tip of a syringe, be considered a risk for HIV if it did poke or puncture my hand alittle?

2) I have read that once blood is in the environment (air), the infectious HIV part starts weakening or dying immediately. So if the syringe is no longer in tact, would that be the case as well?

Mind you, I’m not talking about an intact syringe. I’m talking about the broken piece of a syringe. 

I just don’t want to put anyone in risk here. Thank you for your time. 

As Dr. Hook implied, you apparently are misunderstanding statements you have found bout HIV/STI risks and transmission routes. Probably nobody in the world ever has acquired any such infection on account of just being in the environment of infected (or potentially infected) persons.

Could the "crunchy stuff" have been broken glass or syringe? Of course I have no way of judging, but it wouldn't matter anyway even if the pieces were contaminated with blood. To your specific questions:

1) No this would not be a risk, even if your skin had been punctured.

2) All we really know is that nobody ever has been known to acquire HIV by exposure to blood or body fluids in the environment, even when there have been injuries with potentially contaminated sharp objects. Since it never happens, the biological reasons for absence of risk don't matter. Indeed, HIV rapidly dies with drying or on air exposure, but it doesn't matter one way or the other.

In summary, you're not at risk and cannot possibly put anyone else at risk of any infection on account of these events. You should not be tested for anything. And for the future, please educate yourself about HIV/STI transmission risks. You can safely assume that if you do not have unprotected sex and do not share drug injection equipment with other persons, you will never get HIV. Disregard all other possibilities that may come to mind. And do not read risks like "blood exposure" and assume they mean any and all blood exposures:  they do not. For HIV to transmit requires LOTS of virus having access to certain cells that generally are deep in the body. No sex and no injected blood means no risk.

I hope these comments are helpful. Let me know if anything isn't clear.

As for this question, I understood just about everything you said as a No Risk Event. I seem to have only one clarification question, more on my part. I’d like to clarify that your answer to one of my questions:

I apologize Dr about my anxiety on this. Having these thoughts is so very tiring and wouldn’t wish this feeling on anyone. 

Thank you sir for your time and patience.
