Hi all, I am wondering if anyone has had the mitochondrial dysfunction test from Dr Sarah myhill and whether these tests proved useful? The neurologist Dr Simon Ellis talked me out of these on the pretence that they may actually be a few herring and not very useful in overall diagnosis. Even though I agree with him I don't feel as if anybody- clinician or otherwise knows what's best for a CFS patient? The tests seem a little cheaper now than they were so I am considering it again. As I am interested to see if there are markers in the blood that point to a specific aspect of ME that I have instead of the broader diagnosis that are sometimes attributed through...lack of reputable testing ideas? Anyway I'd be interested to hear people's experiences before I pay for the tests. I'm also looking at Kenny Merlier after someone recommended him on these forums. But costs seem to run into £4000 max when combined with all the test costs. Thanks.
