I apologize that I did not go back and re-read this thread but if you are talking about the beta adrenergic and anti-muscarinic/cholinergic autoantibodies then you cannot get them in the US either. I had the tests done by Cell Trend, a lab in Germany, and sent the blood sample from Los Angeles to Germany which was challenging (and private pay) but was do-able and was worth it in my case.
Also, the test may generate false positives/negatives; OMF proposed a way to improve these tests i.e. remove false positives/negatives [https://www.omf.ngo/2018/02/12/tweak-assay-bolster-disease-detection-stanford-medicine-news-center/]. Anyone fancy trying to get a Member of the European Parliament (Horizon 2020), or a member of Congress/house of Representatives, to support this?
I'd still like to see the autoantibody work pursued i.e. to develop tests and to identify all causal antibodies. If you/a member of your family have an autoimmune disease then it's important. Also, understanding one autoimmune case would clarify the disease mechanism. As Vicky Whittemore (NIH) said at the 2018 Invest in ME Conference we are still at the stage of trying to understand the disease mechanism in ME/CFS.
