p24 (please) - BY

Can you please tell me why this one reactive band is not significant. Isn't this the same p24 tested in the HIV test? Thanks.
Response from Dr. Young
Single western blot bands are usually not significant, this is because human antibodies typically cross react with different proteins. Since the HIV virus is composed of several major proteins, each of which can elicit an antibody response; a true infection with HIV should produce antibodies to several of these proteins - resulting in a Western blot with multiple bands. -BY
