This still leaves room for them CDC and insurance companies to say we are deconditioned. Especially if they do not do blood tests afterwards .
Without a doubt. That doesn't mean they'd be correct, just that they don't care to understand the results of the test. The 2-day test gives much more obvious, and currently understood, results. It's also too damaging, for just that reason, for the most severely ill among us.
I'd do the 2-day test right now (for research) because I think it gives the best information. I'm also reasonably confident I could recover in a few weeks. I would discourage my daughter from doing it, though, because she's currently fully functional and in graduate school. I wouldn't want her to risk all that on a test to destruction. She can't afford to crash at this point in her life.
So, while I agree the 2-day test is best and is the one to use to confirm clear major dysfunction in ME/CFS, I also wonder what the sample set is going to look like if the nature of the testing automatically precludes the most seriously ill and those managing to work who can't risk the possible major crash from participating.
It's a difficult situation. My hope is that 2-day testing done on people like myself who are in a position to risk a crash will provide other less destructive testing. With luck, it will be something that shows up in blood tests. If we need do exercise to get the evidence to show up, let's hope the exercise will be minimal such as Connie's test, so that we don't have to damage people to prove they have ME/CFS.
In the meantime, 2-day testing is the best we have and should be used for research that seeks to determine the nature of our exercise intolerance and PENE.
