Commercial serologic assays for varicella-zoster virus (VZV), which enable reliable determination of VZV immune status and are amenable to automation, are needed. The present study compares the automated performance of the VZV whole-cell enzyme-linked immunosorbent assay (ELISA) Enzygnost anti-VZV/IgG, the Euroimmun anti-VZV ELISA (IgG) based on highly purified viral proteins, and the VZV glyco...

BACKGROUND The dramatic increase in use of the IgG test for toxoplasma, rubella, cytomegalovirus (CMV), and herpes simplex virus (HSV) [TORCH] has led to the requirement for a high-efficiency method that can be used in the clinical laboratory. This study aimed to compare the results of BGI-Array ELISA TORCH IgG (BGI-GBI, China) screening method to those of Virion/Serion TORCH IgG ELISA (Virion/...

Background: The study of antiphospholipid antibodies (aPL), not included in the Sydney diagnostic criteria, syndrome (APS) and systemic lupus erythematosus (SLE) is poorly understood. Objectives: To determine frequency detection IgA-aCL IgA-aβ2GP1 IgG to β2GP1 domain 1 (IgG-aβ2GP1-D1) patients with APS without SLE. Methods: ELISA chemiluminescence assays (CMA) were used test 63 sera patients: 2...

results a total of 205 blood samples obtained from diabetic patients (42 men and 163 women with age range 13 - 60 years) were examined for the presence of toxoplasma antibodies. among patients, 60 cases (29.3%) were seronegative and 145 patients (70.7%) were seropositive, included 53.145 (36.6%) (igg+, igm+) acute phase, 72.145 (49.6%) (igg+, igm-) chronic phase and 20.145 (13.8%) (igg-, igm+) ...

background: the affinity of an antibody to its antigen is a crucial parameter in its biological activity and performance of an immunoassay such as elisa. affinity of most igg specific mabs are often determined by methods which require labeling of either antigen or antibody, and are sometimes difficult to control, do not always lead to the expected signal and often result in immunological modifi...

background toxoplasma gondii has worldwide distribution and is one of the most prevalent infectious agents in humans. objectives the aim of this study was to determine the prevalence of anti-toxoplasma gondii antibodies in hemodialysis patients with chronic kidney disease (ckd) in the hemodialysis unit of fatemeh zahra hospital at the mazandaran university of medical sciences in sari, iran. met...

Focus Technologies developed an indirect immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) and a mu-capture IgM ELISA for the detection of West Nile virus (WNV)-specific antibodies based on a WNV preM/E protein recombinant antigen. Normal and disease state serum panels were used to assess the performance characteristics of the two WNV ELISA kits. Totals of 807 and 1,423 sera were...
