Also, the fact that they are using the XMRV samples means that, if they test positive for TBIs, some percentage of the population characterised as having ME actually have TBIs. These people could then say that the subset with pure autoimmune disease haven´t got ME, they have an autoimmune disease. The important thing is to work out what those people who are labelled as having ME actually have. Then we can argue about who has the ´real´ ME.
