Healthcare providers use antinuclear antibodies (ANAs) to screen and diagnose patients with autoimmune diseases. In the recent years, commercial multiplex ANA kits have emerged as a convenient and fast diagnostic method. Diagnostic testing should follow sequenced algorithms: initial screen followed by specific antibody analysis. Second-level testing as an initial screen for autoimmune disease i...

This case describes a patient with pericardial effusion as a phenomenon of the drug-induced lupus erythematosus (DILE) syndrome due to hydralazine. The relevance of this case report lies in the fact that although hydralazine has been a known causative agent of DILE, its presentation may involve a negative anti-nuclear antibody (ANA) study. Pericardial effusion is a documented adverse effect as ...

BACKGROUND For the serological diagnosis of systemic autoimmune rheumatic diseases, a two-tier approach starting with sensitive antinuclear antibody (ANA) detection by indirect immunofluorescence (IIF) on HEp-2 cells followed by characterization of positive findings with different immunoassays is recommended. To overcome drawbacks of this approach, we developed a novel technique allowing the co...

Virus infected grapevines of the island of Vis display very different symptoms, such as fanleaf, yellow mosaic, vein banding, cane deformities etc. Virus isolates obtained from such plants were tested serologically by immunodiffusion in agar gel with antisera to twelve isometric viruses. A positive reaction was obtained only with grapevine fanleaf virus (GFV) antiserum. The precipitation bands ...

polycystic ovary syndrome (pcos) has been suggested to be linked with autoimmune processes. laparoscopic ovarian electrocauterization has the potency to stimulate more autoimmune reactions in pcos patients. in the present study, we considered anti-nuclear antibodies (anas) as the hallmark of autoimmune reactions, and investigated the serum level of these antibodies in 35 patients with pcos (21-...

Our laboratory has been developing computer programs that help medical technologists improve their performance of the microscope-based immunofluorescence assay for antinuclear antibodies (ANA). This image-based laboratory test has been associated with poor reproducibility. We have previously described our first program, ANA-Tutor, which systematically teaches the ANA test by using approximately...

BACKGROUND The gold standard for antinuclear antibody (ANA) screening is the indirect immunofluorescence (IIF) assay with human epithelial cells (HEp-2). However, a number of substantial disadvantages of manual IIF assays have highlighted the need for the automation and standardization of fluorescent ANA (FANA) testing. We evaluated the performance of EUROPattern Suite (Euroimmun AG, Germany), ...
