all these tests are very hard to get done, especially if outside the US. might just be easier to try the treatments instead, the few that currently exist anyway
That's what I did initially, because in the UK there is no way to test for chronic enterovirus infection (no antibody neutralization tests available), so I just went straight to trying the oxymatrine protocol (which unfortunately did not help in my case).
Later I found a lab in the Netherlands that had an antibody neutralization test for coxsackievirus B (which was only 110 euros, much cheaper than ARUP), and I sent by blood serum sample to them for testing. I came out as having pretty high titers (1:1024) to coxsackievirus B4. Unfortunately that lab has now stopped offering the neutralization test.
I heard that ARUP are no longer accepting blood samples from abroad (but this is unconfirmed), so this creates a big difficulty when ME/CFS patients outside the US want to test for chronic enterovirus infection.
I recently performed an extensive Google search, trying to find other labs in the world which offer coxsackievirus B or echovirus neutralization tests. I actually found several labs, and 9 days ago I emailed them, asking about the cost of the test, and whether they can accept blood samples from abroad. But so far they have been slow in replying.
