Objetivo: O Segundo Consenso Brasileiro de Fator Antinuclear (FAN) em Células HEp-2 ratificou os algoritmos de decisão para leitura dos padrões do FAN na imunofluorescência indireta vistos na primeira edição do Consenso Brasileiro, adicionando ainda um novo algoritmo relacionado com os padrões mistos. Métodos: Tendo em vista a habilidade do teste em detectar autoantígenos nos distintos compartimentos celulares, e não apenas no núcleo, propõe-se novas denominações para este exame laboratorial. Resultados e Conclusões: Como novas denominações algumas sugestões foram igualmente aceitas, dentro do tema “pesquisa de auto-anticorpos contra constituintes do núcleo (FAN HEp-2), nucléolo, citoplasma e aparelho mitótico”. Foram abordadas as principais relevâncias clínicas com os padrões de FAN descritos, facilitando o melhor uso do ensaio pelo médico.
Objective: The Second Brazilian Consensus on Antinuclear Antibodies (ANA) in HEp-2 Cells approved and extended the decision trees developed during the First Brazilian Consensus in order to also offer information about mixed patterns of fluorescence. Methods: Since this test elicits reactions not only to nuclear autoimmune antigens but also to different cell compartments, new denominations for the test were approved. Results and Conclusions: These new denominations encompass variations on the “autoantibody testing against the nucleus (ANA HEp-2), nucleolus, cytoplasm, and mitotic apparatus” issue. Furthermore, major clinical associations were described for each immunofluorescent pattern, facilitating the interpretation of laboratory results in the clinical practice.
