I had HIV EIA (enzyme immunoassay) testing done and it has been non-reactive. What else could be causing the P41 Band (IgG & IgM) to be positive?

In brief: Cross-reactivity

Your body antibodies to a protein that shares some structure with p41.
This is the reason to look for antibodies to multiple HIV proteins, rather than relying on one. Antibodies do cross-react with proteins similar to the one that elicited the antibody.
