Table 2 Overview of (i) the frequency of reporting of the various AC patterns, (ii) the estimation whether a pattern should be classified as competent, and (iii) the clinical relevance (1 is the lowest and 5 the highest score) of the various AC patterns. The reported range represents the minimum and maximum number of responders to the specific questions posed

From: Current laboratory and clinical practices in reporting and interpreting anti-nuclear antibody indirect immunofluorescence (ANA IIF) patterns: results of an international survey

  1. For each question, the results per pattern, are presented as percentages of the total laboratory (competent and expert reported separately) and clinician respondents. The competent patterns are highlighted in bold. The reported range represents the minimum and maximum number of responders to the specific questions posed
