False-positive band in the gp41 region in anti-HIV western blotting.
A consistently positive ELISA reaction and a band in the gp41-region of the HIV-1 western blot were found in repeated serum samples from a healthy pregnant woman. The band was more clearly defined than the HIV gp41 band. Additional ELISA testing and repeated western blot analyses using different test kit batches confirmed our suspicion of a false-positive reaction.
