Factor V Leiden and ANA test
etbest posted:
About 6 months ago I was diagnosed with Factor V Leiden. Does Factor V influence ANA test outcomes? I am trying to understand why my ANA test titer hovers around 1:80 most of the time even though I was diagnosed with lupus, sjogrens and scleroderma over 10 years ago.

I was also diagnosed with MS in 2000. Does Factor V influence blood tests for MS antibodies?

Thank you.
