Hi . Different tests have different window periods. I want to share with you this page from the CDC which gives an overview of the window periods for different tests: https://www.cdc.gov/hiv/basics/hiv-testing/hiv-window-period.html#:~:text=Most%20rapid%20tests%20and%20self,to%2045%20days%20after%20exposure.. Hope this information is helpful, but I also want to note that only trained medical professionals can provide the complete diagnostics. Wishing you the best and please know that this community is here for you. Richard (Team Member)
