As much as 95% of people with CREST syndrome will test positive for centromere B antibodies. People with other forms of scleroderma as well as conditions such as cirrhosis, rheumatoid arthritis, and lupus have also been shown to produce centromere B antibodies. Centromere B antibody testing can aid in diagnosing CREST syndrome as well as differentiating it from other autoimmune disorders with similar symptoms. This test may be ordered as a follow-up to a positive result on an antinuclear antibody (ANA) test, especially if someone has one or more symptoms of CREST syndrome. Turnaround for this test is typically 3-6 business days. Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance. Category: Autoimmune Diseases
