The anticentromere antibody (ACA) test is primarily ordered to help diagnose the autoimmune disorder limited cutaneous scleroderma, a form of systemic scleroderma, and CREST syndrome. The test may be used to distinguish between this and other conditions with similar symptoms.ACA is an autoantibody, a protein produced by the immune system that mistakenly targets the body's own tissues. (For more on this, see the "What is being tested/" section and the article on Scleroderma.)ACA testing may be used to provide a healthcare practitioner with additional information if an ANA (antinuclear antibody) test is positive, especially if the test produces a speckled, nucleolar, or centromere pattern.
