Hey all,
I know you are not sure what anything could be with out medical professionals looking at it. I am wondering if you have any ideas for this? I have Lyme disease and one of my Lupus tests came back positive. How can one of the tests be positive and the rest negative?

Autoantibodies to ssDNA recognize the purine and
pyrimidine bases of DNA. These antibodies are
found in SLE and may be present in patients with
"ANA-negative" SLE. However, high titers are not
specific for SLE or for risk of lupus nephritis
and may be found in drug-induced lupus, rheumatoid
arthritis, and chronic active hepatitis.
