What blood tests indicate scleroderma?
Antinuclear antibody (ANA) testing is the most important blood test to screen for scleroderma and other connective tissue diseases.
What is clinical manifestation of scleroderma?
Scleroderma renal crisis occurs most often in patients with early, rapidly progressing, diffuse skin involvement. However, in 20% of cases these patients have no skin disease, and renal crisis is their first manifestation of scleroderma.
What is a positive SCL 70?
A positive test result for Scl 70 antibodies is consistent with a diagnosis of scleroderma.
How is CREST syndrome diagnosed?
In order to make a diagnosis, they’ll ask you about your family’s health history, look for changes in how thick your skin is, and do some tests. They may also look at your finger under a microscope to check for changes in tiny blood vessels. These start to vanish early on in scleroderma.

Is ANA positive in CREST?
What does the test result mean? If a your ACA result is positive, indicating you have anti-centromere antibodies in your blood, and you have symptoms of CREST, then it is likely that you have limited cutaneous scleroderma.
Can ANA detect scleroderma?
After a thorough examination, the doctor may also order an antibody nuclear (ANA) test, which will let them know if any autoantibodies (blood proteins) are in the blood. However, because our bodies develop antibodies for other reasons, the results of an ANA test by itself don’t determine a diagnosis of scleroderma.
What ANA pattern is associated with scleroderma?
Approximately 95% of people with systemic scleroderma have a positive antinuclear antibody (ANA) test, but so do people with other autoimmune diseases (97% of people with lupus, as an example). People with localized scleroderma usually have negative ANA.
What is a significant ANA titer?
Titers of 1:80 or lower are less likely to be significant. (ANA titers of less than or equal to 1:40 are considered negative.) Even higher titers are often insignificant in patients over 60 years of age.
