I have had Raynauds for 20 years and have tested ANA positive only once in all that time (2001), subsequent tests have all come back negative. However after having a clear Nail Fold Capillary test in 2007 I recently had a repeat test and this time they found changes and evidence of secondary Raynauds.
Can you let me know if this has happened to you, how likely is it that you get an autoimmune condition develop in the future.
