I was tested at ArminLabs with the coxsackievirus test. With the information I gathered, I explained here how the test is supposed to work: The test use the immunofluorescence assay and the cost is 64 euros. They use the test from Euroimmun Lübeck Germany and they "insert" A7 and B1 antigens in the test system. My report, high titers for CVA and CVB: I was also tested at the Utrecht Lab in the Netherlands, which offered (they stop the test at the end of april 2016) a microneutralization test and I was negative for all the CVB except for CVB5 but with a low titer (1:8) that is probably from a past infection, not an active one. In CFS, we know that the microneutralization test is the only one that showed a real correlation with an enterovirus infection in a non-cytolytic form. I don't understand why I'm positive for the CVB and CVA. Moreover, the CVA types are not linked to CFS. I was thinking that the result are due to a cross-reaction with several enterovirus types. Who was tested with the coxsackievirus at ArminLabs? What are your result? Who was positive for the CVA with the ArminLabs test? If we can compare with a microneutralization test (Arup Lab for example), maybe we can find if the ArminLabs test is reliable about the detection of non-cytolytic coxsackievirus infection.
