I had labs ordered by my Rheumatologist in March 2016. The results were all in normal range (including ANA and SCL-70 Antibody). The only lab result that was out of range was my Vitamin D...it was 11!
Fast forward to July 2016, my rheumatologist sent me for follow up labs. My Vitamin D was normal but my SCL-70 was Positive 2.4 (or 240?). My ANA was again negative. I've read that a negative ANA and positive SCL-70 is suggestive of Scleroderma and the reason my SCL-70 was negative in March was either a false negative or Scleroderma was "active" at the time.
Can someone please help me understand? I don't want to depend on Google for information so I'm hoping this forum can help! I haven't heard from my Rheumatologist yet, but I'm nervous about the results. I've heard scleroderma is very serious! I do have several symptoms of it as well. Thank you for reading my post.
