What does an elevated ANA titer indicate in a person with Raynaud's?

Answer by  sar (227)

Raynaud's can occur idiopathically (primary Raynaud's) or it can be caused by some instigating factor (secondary Raynaud's). Secondary Raynaud's is associated with autoimmune disorders. It's often the first symptom of these types of conditions. The ANA test is often used to screen for those same disorders. An elevated ANA titer indicates that the Raynaud's is secondary rather than primary.

An elevated ANA titer is often present in Raynaud's and may possible indicate the presence of an autoimmune disease process.
