Can someone transmit hiv when they are non reactive?
If somebody has taken an HIV test and received a non-reactive result this usually means they do not have HIV.
There is one exception to this where they have recently caught HIV but it is too early to show up in the test.
For HIV tests done in a laboratory it takes 7 weeks for the HIV infection to show up in the test.
For HIV tests done at home it takes 12 weeks for the HIV infection to show up in tests.
If a person has been at risk of HIV then we advise that they test immediately and then again in 7 weeks if using a laboratory test or 12 weeks if using a home test.
