My GP ordered ANA screen and rheumatoid factor as my joint symptoms have worsened and she wasn't sure if I'd ever been tested since ME /CFS diagnosis. The screen came back negative.
The results are all marked as normal. However, I do know lab reference ranges sometimes need digging under a little (I have auto immune thyroiditis but it wasn't picked up until one GP noticed I'd been borderline hypo for years). At the same time, I don't want to go looking for problems where there are none.
Wondering if anybody knowledgeable can help me out?
The only ones that aren't marked as less than 0.2 are:-
DNA binding autoantibodies 1 iu/ml (range < 9.99)
Serum SSA 60 (RO) Ab conc 0.3 AI ( < 0.99)
Sm/RNP antibody 0.6 ( < 0.99)
Chromatin IgG Ab 0.2 (< 0.99)
Anti CPP is < 0.5 (< 2.99)
My Rheumatoid factor is reported as < 15 iu/ ml so normal against reference range < 20.
Many thanks
