Does getting a non-reactive result on an hiv test mean negative? even with that result can you still be infected?

Yes, : Yes, non-reactive is negative. But you need to know a little more. There are two main ways of looking for HIV infection--by looking for the body's response to the virus (antibody tests) and looking directly for the virus. In the case of antibody tests (such as elisa and western blot) it may take 6-12 weeks to become "positive" (or rarely up to 6 months), so you can be "non-reactive" shortly after catching the disease, but still be harboring it. The test for the virus itself becomes positive much earlier in an infection, but is not generally described as "non-reactive" when it is negative.
