BacteriologyImproved Early Detection of Focal Brucellosis Complications with Anti-Brucella IgGTo evaluate the associations of inflammatory factors and serological test results with complicated brucellosis, we recruited 285 patients with a diagnosis of brucellosis between May 2016 and September 2019. The patients were subsequently classified into two groups according to the presence of complications. We collected demographic and clinical information and routine laboratory test results in addition to anti-Brucella IgG and...
ImmunoassaysA Method To Prevent SARS-CoV-2 IgM False Positives in Gold Immunochromatography and Enzyme-Linked Immunosorbent AssaysWe set out to investigate the interference factors that led to false-positive novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) IgM detection results using gold immunochromatography assay (GICA) and enzyme-linked immunosorbent assay (ELISA) and the corresponding solutions. GICA and ELISA were used to detect SARS-CoV-2 IgM in 86 serum samples, including 5 influenza A virus (Flu A) IgM-positive sera, 5 influenza B virus (...
ImmunoassaysComparison of Different Commercially Available Enzyme-Linked Immunosorbent Assays with Immunofluorescence Test for Detection of Phase II IgG and IgM Antibodies to Coxiella burnetiiSeveral commercially available enzyme-linked immunosorbent assays (ELISAs) for the detection of phase II IgG or IgM antibodies against Coxiella burnetii were compared. In addition, an indirect immunofluorescence test was used as a confirmation test. In all, 70 serum samples for IgG and 43 serum samples for IgM were tested. The ELISAs showed large differences in...
