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 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 کاملStaining Pattern Classification of Antinuclear Autoantibodies Based on Block Segmentation in Indirect Immunofluorescence Images
Indirect immunofluorescence based on HEp-2 cell substrate is the most commonly used staining method for antinuclear autoantibodies associated with different types of autoimmune pathologies. The aim of this paper is to design an automatic system to identify the staining patterns based on block segmentation compared to the cell segmentation most used in previous research. Various feature descript...
متن کاملCharacterisation of Liver membrane autoantibodies determined by indirect immunofluorescence.
Indirect immunofluorescence studies were performed using sera and IgG-Fab2 fragments from patients with chronic active hepatitis (CAH) who were positive for a liver membrane antibody (LMA). The specificity was investigated using hepatocytes from humans as well as rabbit, rat, guinea pig and monkey. Only sera also positive for smooth muscle antibody gave staining of lymphocytes and absorption wi...
متن کاملAntinuclear antibodies by indirect immunofluorescence : optimum screening dilution for diagnosis of systemic lupus erythematosus.
BACKGROUND & OBJECTIVES Antinuclear antibodies (ANA) are serological hallmark of systemic lupus erythematosus (SLE). Conventionally, the test is carried out on human epithelial cells (HEp2) by indirect immunofluorescence (IIF) technique. Since culturing and maintaining HEp2 cells in the laboratory are labour intensive, in-house assays have given way to kits manufactured by commercial companies....
