That is an excellent question and one that is best addressed by your primary care doctor
or another medical care professional who can discuss all your concerns and decide whether any testing is required. Based upon the history you have provided, it is unlikely that what occurred should make you concerned. On the other hand, if there is something that happens that makes you uncomfortable or that seems unhygienic to you, then it is important that you discuss it at the time that it happened with the phlebotomist as this could be occurring commonly and it is not appropriate that he or she is performing their job in an unsanitary way. It also may be making other people feel uncomfortable and they may not say anything so you would be helping many people by discussing this with the phlebotomist at the time that it occurred. Also, if you take a urine test, it is important that you do not touch the cup at all as this can cause the urine test to become dirty and a false positive. I would suggest waiting for the results but you may consider retaking the urine test if it does show something because it may not be clean as mentioned before. I recommend seeing your doctor to discuss this further.
