^aMethod should be specified either along with the test name or in the legend of the report. ^bRefers exclusively on IIF test on HEp-2 or HEp-2000 substrate. ^cRefers to solid-based screen tests commercially available under the common name CTD-screen. ^dENA screen test refers exclusively on test comprising following antigens: SS-A (Ro) (when there is no distinction between Ro52 and Ro 60) or SS-A (Ro60) and Ro52 (TRIM21), separately; SS-B (La); Sm (or SmD according to manufacturer specification); RNP (U1-RNP or Sm/RNP, according to manufacturer specification); Scl-70 (Topo-1) and Jo-1. In the case that the screen test includes additional antigens that are not included in ENA term, use the nomenclature given under number 2. ^eSS-A (Ro) – if there is no distinction between Ro52 and Ro60; ^e Alternatively, anti-SmD in the case that manufacturer declares specificity exclusively for SmD antigen. ^fanti-RNP term comprises both anti-U1-RNP and anti-Sm/RNP. IIF – indirect immunofluorescence. HEp-2 – human laryngeal epidermoid carcinoma cell line type 2 substrate. CTD – connective tissue diseases. ENA – extractable nuclear antigens. RNP – ribonucleoprotein complex.
