IgG, IgM and IgA levels, as well as IgG1-4 subclasses and peripheral blood lymphocyte proliferative responses against core, envelope and NS3 antigens were assayed by ELISA and CFSE staining ...

A hepatitis A immunoglobulin G (IgG)-positive and immunoglobulin M (IgM)-negative test result may indicate immunity to hepatitis A. Learn more here.

IgG, IgM and IgA levels, as well as IgG1-4 subclasses and peripheral blood lymphocyte proliferative responses against core, envelope and NS3 antigens were assayed by ELISA and CFSE staining ...

(HealthDay)—A noninvasive oral fluid-based immunoassay has high sensitivity and specificity for identifying recent and past hepatitis E virus (HEV) infection, according to a study published in ...

They showed that although IgA, IgM, and IgG target overlapping sets of microbes, the role of IgA is distinct from IgM in restraining commensal microbes in the gut, ...

To be diagnosed with IgA deficiency, patients must be over 4 years of age and have no IgA as determined through a blood test, as well as normal serum levels of IgG and IgM, without other known ...

Study authors measured the levels of immunoglobulin M, IgG, and IgA in healthcare workers, and observed fast decay of 2 antibodies which has implications for further seroprevalence studies.

The results have shown that, during the early convalescence period, anti-RBD plasma IgA antibodies can contribute to the neutralizing capacity for many individuals, alongside IgG and IgM isotypes.
