Welcome to ANApatterns.org, the official website for the International Consensus on Antinuclear Antibody (ANA) Patterns (ICAP). ICAP was initiated as a workshop aiming to thoroughly discuss and to promote consensus regarding the richness in nuances of morphological patterns observed in the indirect immunofluorescence assay on HEp-2 cells. The ICAP initiative was implemented at the 12th International Workshop on Autoantibodies and Autoimmunity (IWAA) by members of the Autoantibody Standardization Committee (ASC), a subcommittee of the International Union of Immunological Societies (IUIS) (403) 258-1132 and affiliated with the Centers for Diseases Control and Prevention (CDC). The ICAP committee is operating as an ASC sub-committee.

Satoh, C.A. von Mühlen, and L.E.C. Andrade. Report of the First International Consensus on Standardized Nomenclature of Antinuclear Antibody HEp-2 Cell Patterns (ICAP) 2014-2015 (Front. Immunol. 2015, Aug 20;6:412).

Representative images, based on pixel dimension, resolution, and size, were submitted online by ICAP members. For each pattern, between 2 to >10 images were submitted. Most patterns had average 5 to 8 images. More than ten ICAP members voted for the best three images representing each pattern and the top two images for each pattern are displayed on this web site.
