In-House RT-PCR Assay for Detection of Human Immunodeficiency Virus Type 1 Infection [PDF]

, 2009
Serologic assays are commonly used for screening (ELISA) and for confirmation (Western blot) of HIV-1 infection; however, both assays have potentially yielded the false-positive or false-negative results.

Diagnostic value of antibody testing in comparison with lung scan and PCR in patients suspected of having COVID-19

Iranian Journal of Microbiology
Background and Objectives: SARS-CoV-2 is a newly discovered viral infection. It’s still unclear how antibodies react in infected individuals, and there is not enough evidence to support the clinical use of antibody examination.

Appropriate Serological Testing in Pregnancy [PDF]

Vox Sanguinis, 1992
We read with interest the recent report by Garner et al. [l], in which anti-E was detected early in pregnancy solely through the use of enzymetreated red blood cells (RBC). The serological reactivity of this anti-E changed dramatically during pregnancy; the antibody became detectable by the indirect antiglobulin test, and at 37 weeks’ gestation had a ...

Laboratory perspectives for Leprosy: Diagnostic, prognostic and predictive tools

Indian Journal of Pathology and Microbiology, 2022
The diagnosis of leprosy poses several challenges. The bacillary load, serology, and tissue response are determined by the host immune status, which make individual tests unsuitable across the spectrum.

Serologic Testing for Celiac Disease [PDF]

Clinical Chemistry, 2002
We read with interest the report by Martini et al. (1). The authors compared the accuracy of five commercially available IgA anti-tissue transglutaminase (anti-tTG) ELISAs with data from anti-endomysial antibodies (EmAs) in the diagnosis and follow-up of adult patients with celiac disease (CD) and supported the superiority of the EmA test over ELISAs ...

Identification of the capsule type of Pasteurella multocida isolates from cases of fowl cholera by multiplex PCR and comparison with phenotypic methods

Brazilian Journal of Poultry Science, 2014
The ability of Pasteurella multocida to invade and multiply in its host is enhanced by the presence of the capsule, one of the most important virulence factors for this bacterium. Capsular typing methods are often used in epidemiological and pathogenesis
