Characteristics of False-Positive Alarms in the BacT/Alert 3D System

Microbiology Spectrum, 2022
The BacT/Alert system has been used for detecting the presence of bacteria in various clinical settings as well as in blood services, but it is associated with a relatively high incidence of false-positive results.

Yersinia enterocolitica serotype O:9 cultured from Swedish sheep showing serologically false - positive reactions for Brucella melitensis

Infection Ecology and Epidemiology, 2012
In a herd of 20 sheep in Sweden, a country where brucellosis has never been diagnosed in sheep or goats, a total of six sheep were found serologically positive to Brucella melitensis in two different rounds of sampling. Yersinia enterocolitica serotype O:

Preventing intense false positive and negative reactions attributed to the principle of ELISA to re-investigate antibody studies in autoimmune diseases

JIM - Journal of Immunological Methods, 2014
To study the possible involvement of potential environmental pathogens in the pathogenesis of autoimmune diseases, it is essential to investigate antibody responses to a variety of environmental agents and autologous components.

Accounting for False Positive HIV Tests: Is Visceral Leishmaniasis Responsible? [PDF]

PLoS ONE, 2015
Co-infection with HIV and visceral leishmaniasis is an important consideration in treatment of either disease in endemic areas. Diagnosis of HIV in resource-limited settings relies on rapid diagnostic tests used together in an algorithm.

Brucella melitensis B115-based ELISA to unravel false positive serologic reactions in bovine brucellosis: a field study [PDF]

BMC Veterinary Research, 2020
Background Brucellosis is a zoonosis whose incidence is not declining worldwide despite the global effort to control the disease. Accurate and precise diagnosis is a crucial step in any prophylaxis program but single tests to unequivocally detect animals

Clinical characteristics and cause analysis of false-positive results in treponemal testing among patients

Annals of Medicine
Background Currently, there is a dearth of systematic research data on the phenomenon of false-positive reactions in treponemal tests. The aim of this study is to analyze the clinical characteristics and influencing factors associated with false-positive

High prevalence of human anti-bovine IgG antibodies as the major cause of false positive reactions in two-site immunoassays based on monoclonal antibodies

Journal of immunoassay & immunochemistry, 2004
Udgivelsesdato: 2004-nullA sandwich ELISA for quantification of the endometrial protein PP14 revealed false positive reactions in 81% of male sera (n = 54). The PP14 ELISA was based on two monoclonal antibodies (Mabs) with different epitope specificities-

The occurrence and treatment of false positive reactions in enzyme-linked immunosorbent assays (ELISA) for the presence of fungal antigens in clinical samples

JIM - Journal of Immunological Methods, 1979
Non-specific positive reactions have been revealed in enzyme-linked immunosorbent assays (ELISA) of sera for the presence of fungal antigen. These false positives were recognized by their occurrence in tests for both Candida albicans and Aspergillus ...

False-positive results of galactomannan assays in patients administered glucose-containing solutions

Scientific Reports
Galactomannan (GM) is a polysaccharide cell wall component released by Aspergillus spp., and an immunoenzymatic GM assay is used for the diagnosis of invasive pulmonary aspergillosis. We evaluated the cause of strong positivity for GM in patients with no
