There seems to be a natural tendency among some skeptics and questioners that when part of a theory or concept is proven to be flawed, any and all other aspects about it should be dismissed as well.
This certainly seems to be the case for some AIDS dissidents when it comes to discussions about the significance of certain laboratory markers, in particularly certain immune cells involved in fighting infections, called CD4 t-cells. CD4 counts are, arguably, considered by mainstream AIDS experts as the single most important measure of disease progression and risk for patients acquiring opportunistic infections.
