Diagnostic test Patent produced! This is high tech stuff. De Meirleir quite awhile ago proposed that ME/CFS patients had high rates of cell apoptosis (suicide) and that they could trace that, I think, by looking at actin. This appears to be something different but it does assert that cells are dying in CFS patients blood in high amounts and something different happens in them when they do die - which is released into the blood - and can be picked up by this test. They appear to do this on the chromosome level - it really sounds like cutting edge stuff.
