Use

Anti-ENA6 Plus DFS70 is designed to facilitate the proper triage of patients with positive Anti-Nuclear Antibodies (ANA) by identifying those most likely to benefit from a rheumatology specialist. It detects the novel Anti-DFS70 along with 6 other clinically useful autoantibodies to ENA, which may help identify systemic lupus erythematous (SLE), mixed connective tissue disease (MCTD), Sjogren's, systemic sclerosis, and idiopathic inflammatory myopathy (IIM). Positive Anti-DFS70 antibodies in isolation may help identify individuals who do not have an AARD (ANA-associated rheumatic disease), especially in the absence of significant clinical findings.

Special Instructions

For optimal results, it is important that serum is separated from cells within one hour of collection and transferred to a plastic transport tube before shipping.

Limitations

This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration. The presence of Anti-DFS70 Abs in isolation may help identify individuals who do not have AARD, especially in the absence of significant clinical findings. Anti-DFS70 Abs are detectable in 2% to 22% of healthy individuals and in less than 1% of patients with ANA-associated rheumatic disease.
