The results of the antinuclear antibody, ANA, can be very misleading. It is just one of the many tests that doctors use to determine if Raynaud’s is primary or secondary to an underlying condition such as lupus, scleroderma, or RA. The ANA can be positive for many reasons. Your doctor is the best person to put the information from lab tests and the clinical exam together and determine if an autoimmune disease is present.
Most people with primary Raynaud’s will have a negative ANA but there are exceptions. Most doctors will closely monitor a person with a positive ANA and Raynaud’s to see if an autoimmune disease develops.
Thank you. I have tested positive for ANA on many occasions (the first time, 11 yrs ago) but have never developed a major condition such as lupus, scleroderma, or RA, thank God. Because I have tested positive with ANA more than twice I was diagnosed with a minor condition called Undifferentiated Connective Tissue Disease.
I gave birth six months ago, and since then developed additional symptoms in line with lupus, scleroderma, or RA. So of course, given my Raynauds and ANA I am now afraid of developing one of them. My lab test remain unchanged, thank God, but symptoms are still there. I also read that most people who have developed Raynauds at an early age (which I did) remain with primary Raynauds and never develops into anything else. I really hope this is the case for me.
