P24 antigen and HIV 2 virus

[Skir1984]

Hi, as there is no p24 antigen in HIV 2 virus. How can we say 4th generation Combo test (which tests for p24 and antibodies) is conclusive at 28 days? I heard that antibodies to HIV 2 virus will take much time to form than HIV 1. Can someone enlighten me on this topic?

This is not a biology class where you can learn how to make a home hiv test or how to challenge the scientists who got FDA approval for the test that you bought. You can ask the manufacturer about their device instead, although you don't ask your doctor for something like a blueprint of the Xray machine that he uses to check your bones etc. so it is hiv fixation to wonder how the test works.
All you needed to know yesterday is you don't have hiv.     https://www.medhelp.org/posts/HIV-Prevention/HIV-risk/show/3065544
