I encountered a needle stick from a needle of a known Herion user back in July of 2011. The stick drew some blood from my for finger. I had no idea, at that time, when the needle was last used. Subsequently, I have tested HIV and HCV negative at 2.5 months, 4.5 months and 6 months all using the 3rd generation Elisa Test that test for both IgG and Igm antibodies. I'm unsure of the HIV status of the drug user. I've had ongoing sinus problems since December. However, I don't remember any other problems since my exposure other than fatigue which my GP found to be very low B12. I'm a 50 year old male. Can I relax with the results that I received or is there another test I should be taking?
