Respected doctors,
I am 40. Two years ago I did my first ANA (fana) lab tests. Ana test speckled was 1:80, and RNP 1.0 All other results came out negative (U1-RNP, CCP, IgG-abs, ds-DNA-ab, chromatine abs, SS-A/Ro(60kD), La/SS-B, Sm (B'B/D), U1-RNP/SM, Scl-70, Jo-1/Histidyl-tRNA-Synthet., Ribosomal P-protein abs, c-ANCA, p-ANCA, Cardiolipin-Ig-(G/M/A), B2-glycoprot.-1-ab, Lupus-anticoagulant, MAK/TPO-abs).
After 7 months I repeated the ANA test, everything remained the same, except RNP 1.1.
A hew days ago I did my third ANA test, everything remained the same again, except RNP 1.5.
What could this possibly mean? Why is RNP rising? Is it an indication for SLE or MCTD, although U1RNP is negative? 
My TSH was 7mU/L and FT 10pmol/L, after one year of taking Euthirox my TSH i 5mU/L and F4 11pmol/L. I don't know if this coud be a triigger. Pituitary gland MR normal. 
Thanks very much in advance
