Why does the body p24 antigen disappears after a few weeks?

Hi, I'm sorry my English worse. My question is: Why does the body p24 antigen disappears after a few weeks? This is due to formation of antibodies? Thx

P24 Antigen exists before the body reacts to HIV. When it reacts it produces antibodies against the HIV, which cause the P24 Antigen to 'disappear' as you put it.

Sorry have just re-read my answer and it isnt clear. It always exists, but at higher levels after contracting HIV until the antibodies kick in.
