(for MCTD) anti-La/anti-SS-B (for Sjögren's) anti-Ro/anti-SS-A(for Sjögren's) anti-Scl70 (for Scleroderma) anti-Jo (for Dermatomyositis) Sensitivity and specificity of these tests depends on the type of assay employed, and will therefore vary by lab. The following table illustrates the sensitivity and specificity of ENA antibodies at detecting SLE with the ELISA technique. In addition, the use of ENA testing has also been used for the study of wheat related disorders such as celiac disease. A study conducted in 2018 screened patients with wheat related disorders for 10 anti-ENA antibodies. SSA (Ro) SSB (La) RNP/Sm Jo-1 Sm Scl-70 Chromatin Centromere Histone RNA polymerase III 73% of celiac disease subjects tested positive for anti-histone and was the most prevalent, which is typically associated with drug-induced lupus erythematosus. This implicates a high probability of an autoimmune disorder in patients with wheat-related disorders. References External links Rheumatology
