Original Approach for Automated Quantification of Antinuclear Autoantibodies by Indirect Immunofluorescence
INTRODUCTION Indirect immunofluorescence (IIF) is the gold standard method for the detection of antinuclear antibodies (ANA) which are essential markers for the diagnosis of systemic autoimmune rheumatic diseases. For the discrimination of positive and negative samples, we propose here an original approach named Immunofluorescence for Computed Antinuclear antibody Rational Evaluation (ICARE) ba...
متن کاملDetection of Antinuclear Antibody in Childhood Rheumatic Diseases by Immunofluorescence Assay and Enzyme Immuno Assay
Background: Anti-nuclear antibodies (ANAs) are specific antibodies directed against a variety of nuclear antigens. Indirect immunofluorecence (ANA-IFA) and Enzyme Immunoassay (ANA-EIA) are commonly used methods for ANA detection. The positivity of ANA-IFA using HEp-2 cell substrate is 90-100% in systemic rheumatic diseases. On the other hand positivity of ANA-EIA is found to be much lower in di...
متن کاملAutomated Indirect Immunofluorescence Evaluation of Antinuclear Autoantibodies on HEp-2 Cells
Indirect immunofluorescence (IIF) on human epithelial (HEp-2) cells is considered as the gold standard screening method for the detection of antinuclear autoantibodies (ANA). However, in terms of automation and standardization, it has not been able to keep pace with most other analytical techniques used in diagnostic laboratories. Although there are already some automation solutions for IIF inc...
متن کاملDetection of specific antinuclear reactivities in patients with negative anti-nuclear antibody immunofluorescence screening tests.
BACKGROUND For detection of anti-nuclear antibodies (ANAs) and antibodies to extractable nuclear antigens (ENAs), samples frequently are screened with indirect immunofluorescence (IIF); further determination of anti-ENA antibodies is performed only when the result is positive. However, because anti-ENA reactivities are found in samples with low fluorescence intensities, we determined anti-ENA a...
متن کاملDetection of antinuclear antibodies by solid-phase immunoassays and immunofluorescence analysis.
BACKGROUND Antinuclear antibodies (ANAs) are associated with several inflammatory rheumatic diseases. The aim of the present work was to evaluate enzyme immunoassays (EIAs) and compare them with classic immunofluorescent analysis (IFA) for the detection of ANA. METHODS Seven enzyme immunoassays were used in this study. All assays were applied as described by the manufacturers. Three populatio...
