A Comparison of Anti-Nuclear Antibody Quantification Using Automated Enzyme Immunoassays and Immunofluorescence Assays

<table>Analytical flowchart. EIA with a combination of dsDNA, ANA Symphony, and the 7 subantigens (SmD, U1RNP, SSA/Ro, SSB/La, Scl-70, CENP-B, and Jo-1) is referred to as “Combined EIA.” IFA tests were performed at a primary laboratory (Gentofte Hospital) and a secondary laboratory (Statens Serum Institut). NEG: negative, EQV: equivocal, POS: positive, and ND: not determined.</table>
