A member asked:
Hiv 1&2 antibody production can get delayed by factors like immunity, medications, other diseases, treatments etc..same is applicable to p24 antigens?

Conclusive at 4 wk: Your opening statement is mistaken: HIV antibody development is NOT delayed by any known immune problems, medications, etc. The antibody-only HIV tests always are conclusive by 6-8 weeks after exposure. If somehow antibody were delayed, p24 antigen would appear sooner, not later. The Ag-Ab (4th generation) HIV tests therefore are ALWAYS 100% conclusive any time 4 weeks or more after catching HIV.

What kind of immunedefiencies would delay antibody production in modern HIV tests.
If someone had an acute HIV infection, would Re-exposure to the same viral strain slow their seroconversion/production of IGM/IGG antibodies? Or delay detectable P24 in the blood? Could CMV/HIV co-infection also cause delay in antibody production?
