First off, I would suspect it is highly unlikely that the lancet was contaminated. This would be a major infection control error and a complete break in standard protocol.
Such an exposure could be a source of transmission of Hepatitis B, hepatitis C or HIV, but the likelihood of this having happened is extremely unlikely.
Always ask if you need clarification/more information.
POSITIVE feedback & a BONUS are warmly appreciated. Please note that answers are for information only, do not take the place of an IN PERSON assessment by your doctor,and does not establish a patient-physician relationship.
If you are implying that someone purposely used a contaminated lancet- well that would be possible and could transmit infections as I noted above.
Again, highly unlikely, and that would imply some seriously malicious behavior.
It would not need to be deep to transmit infectious virus, if a lancet was contaminated.
I am sure you can realize how paranoid this sounds.
