Anti-centromere antibodies are found in approximately 60% of patients with limited systemic scleroderma and in 15% of those with the diffuse form of scleroderma. The specificity of this test is >98%. Thus, a positive anti-centromere antibody finding is strongly suggestive of limited systemic scleroderma.
Since this activity occurs in the nucleus of the cell ATA is a form of antinuclear antibody.

Of the antibodies, 90% have a detectable antinuclear antibody. Anticentromere antibody is more common in the limited form (80–90%) than in the diffuse form (10%), and anti-scl70 is more common in the diffuse form (30–40%) and in African-American patients (who are more susceptible to the systemic form).

CREST is not easily diagnosed as it closely mimics symptoms of other connective tissue and autoimmune diseases. Diagnoses are usually given when a patient presents two or more of the five major clinical symptoms. [5]
