What's the risk of HIV being transmitted from a finger prick or blood draw? I had my 6-week negative 4th generation Cmia test and it came back non-reactive. Everyone said that the accuracy of the test is high at that point and some say I don't even need to test again at 3 months because its already conclusive. But 2 weeks later, I was struck by the flu. I had headaches, fever, chills. I don't think I have a sore throat but I feel thick mucus accumulation at the back of my throat. I don't see any reason for this except I'm seroconverting late which nullifies what everyone says that a 4th gen test is conclusive at 6 weeks, or I could have contracted HIV from the tests that were done to me previously. I've had several tests done prior to the 6 week test, some were finger prick tests from HIV testing centers in our country, and some were blood draws from hospitals. I'm worried because I didn't really see whether new needles were used during my tests. These tests range from 2-4 weeks before my flu symptoms kicked in which is the perfect time for ARS to appear. I'm very worried so please help me clarify a few things: What's the risk of transmission from a finger prick or blood draw? Hypothetically speaking, let's say the nurse forgot and reused a needle used previously on an HIV+ person. Can that needle infect the next person? What are the chances?
