Question

I'm feeling really anxious because a while back, I had a risky encounter with someone whose HIV status I don't know. It's been 180 days since then, and I did an HIV test on day 179. The test I took was the HIV 1 and 2 p24 CMIA, and the result came back negative with an index value of 0.09. I'm trying to understand more about the window period for HIV testing and whether the CMIA test is as reliable as the ELISA test. Also, does taking the test two days earlier, like on day 179, affect the accuracy at all? I had multiple tests throughout this periodone at three months with an index of 0.07 and another at day 42, which was also negative with the same index value. Can you help me make sense of all this?
