ENA (Extractable Nuclear Antigens)
Antibodies to SS-A (Ro) and SS-B (La) are mainly associated with Sjogren’s syndrome but may be found in SLE and less frequently in other autoimmune disorders. Anti-Sm and anti-RNP are associated with SLE and mixed connective tissue disease. Anti-Scl 70 is associated with scleroderma while anti-Jo-1 is seen in dermatomyositis.
All tests are compromised by prolonged transit times. For this reason, date of bleed and date of postage must be provided with each request.
