Lupus question
I am currently being treated for crohns
disease with prednisone,and I am also
being tested for lupus. Will the ANA
screen or any other test for lupus come
back as a false negative because of the
prednisone that I am taking?

No, most of the tests will not come back
as a false-negative because even small
amounts of antibodies (ANA, anti-dsDNA,
anti-ssDNA, anti-Sm,) in the blood or the
skin(lupus-band-test) will still be
detected.
