Sorry to hear about your aunt. My condolences. I think your misinterpreted my intent, I would dearly love a good diagnostic test for ME/CFS and agree research has been hugely underfunded.

I have followed closely the research for many years and there has been false promise of good diagnostic tests previously. What I'm arguing for is that we need a test that is specific for ME/CFS. E.g. it will test positive for a patient with ME/CFS regardless of they are obese or not, but more importantly it will not test positive for everyone who is obese. This is known as the sensitivity and specificity of the test.

What I've seen in the past is some previous ME/CFS tests show positive for groups with related symptoms but who don't have ME/CFS. This then becomes a worthless diagnostic tool. For example this would not have helped your aunt.

Hope this explains my thoughts!
