Anti-DFS70 antibodies may help identify individuals who do not have an ANA-associated Autoimmune Rheumatic Disease (AARD) especially in the absence of significant clinical findings.1 Anti-DFS70 Ab, especially when positive in isolation (i.e. in the absence of AARD-associated autoantibodies), may prevent unnecessary referrals and examinations of ANA-positive individuals.2
This test should be used with clinical findings and other autoimmune testing; it cannot be used alone to rule out autoimmune disease.
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
Enzyme-linked immunosorbent assay (ELISA)
Anti-DFS70 antibodies target the dense fine speckled protein of 70 kDa which is identical to Lens Epithelium-Derived Growth Factor or transcription co-activator p75 (LEDGFp75). They are detectable in 2% to 22% of healthy individuals and in less than 1% of patients with AARD are of unknown clinical significance.
