Does the route of transmission affect the window period at all? For example, would a needle exposure versus a sexual exposure take longer to show positive on an antibody test or vice versa? Or does that not affect the window period at all?
Response from Ms. Southall
Hi No it does not. The guidelines for HIV testing are to be initially tested at 3 weeks then again at 3 months, if both of these tests are negative then so are you, as long as there were no other types of exposure during that 3 month period, if so then the timing starts over again.
What is being tested is the body making antibodies against HIV. This window period is the average time it takes for antibodies to be made, 3 weeks to 3 months and the mode of transmission doesn't affect that.
Be well and stay safe, Shannon
