Hello, I hope I meet a few people here who know their stuff better than me. In my lab report, the ANA (iFT) came out negative and the dsdna (LIA) came out slightly positive. Reference value. Was <27 it came +32. The reason I had it checked was a redness on my face that is still indefinable to this day. After that I ordered another three tests, at different intervals the ANA was still negative and the dsDna was always between 22 and 24 (all 3 ELISA). Doctors don't say SLE because the other symptoms are missing. Incidentally, ENA was also negative 3 times with LIA. Can you explain to me how it turned out this way in the first test? Do you think it was a laboratory or . KIT error? Doctors, in
