What is the ‘window period’?
This is the time from the HIV infection to when a test can correctly give a positive result. You may test positive with INSTI® HIV Self Test in as little as 21-22 days after infection1, however it can take as long as 3 months to produce a positive result.
A negative result may not be accurate until 3 months after the infection. If you think you have been exposed to HIV within the last 3 months, and your results are negative, you should test again after at least 3 months have passed since your exposure.
