There's a reason (probably many reasons) why the body has evolved over millions of years to make the stuff that floats around in our bloodstream. Simple correlations between seeing one thing in one test with some disease or syndrome doesn't mean that one is the result of the other.
The human body is extremely complicated. While we've got to start somewhere in figuring out treatments, we (and especially the press) need to recognize that there's more that we don't know than we do.
Cheers,
Scott.
