Web25 mrt. 2024 · HEp-2 IIFAs are commonly used for antinuclear antibody (ANA) detection, the outcomes of which are integrated in diagnostic and classification criteria for many systemic autoimmune diseases. The HEp-2 IIFA test can also provide fluorescence patterns that may be clinically relevant for disease classification. WebAutoantibodies targeting antigens in the nuclear region in the HEp-2 cell line substrate using the indirect immunofluorescence assay (IFA) have traditionally been called antinuclear antibody (ANA). ANA is the commonly performed antibody test in the initial evaluation of patients with systemic autoimmune rheumatic diseases (also referred to as connective …
