Hi all, CFS for 18 months now. Massive initial crash slowly improving 1-2% a month since crash. Many areas have improved for me. Less aches, better sleep, less fatigue but I still have CFS. Anyway I'm in a study that Bond university has been conducting over a 2 year period here in Australia. Thought I would share my results with you all. They are looking at NK cell function, basically trying to find a way of diagnosing the illness and not curing it yet. Natural Kill cell Activity (%) 4.3 reference range 13.8 - 34.8 Natural killer Dim Cell(%) 78 reference range 60-88 Natural killer Bright Cell (%) 3.75 Reference range 5-15 definitely shows we have problems with our bodies/immune systems.
