Ok, thanks alot. Now I know, I won't worry about it anymore.
Like teak said, the lancets cannot be reused. Once the spring has sprung, the needle-like part is inside the housing unit for good. Also, FYI...even IF a lancet was reused on you seconds after an infected person, it STILL wouldn't be a risk.
A lancet creates a TINY shallow opening in the skin to obtain a capillary sample. This would NEVER be sufficient enough to cause a risk, plus, the amount of blood present on the lancet would also not be sufficient enough to cause a risk.
Don't give this another thought. In NO way were you at risk.
No there is not an HIV issue and the auto pens cannot be reused.
