COVID-19 and Antibody tests explained: IgM and IgG antibodies to Coronavirus SARS-CoV-2 IgG antibodies and why the receptor-biding domain of the spike protein is so important Beckman Coulter's Suite of COVID-19 Testing Solutions Beckman Coulter offers a menu that matters for...
The rationale for focusing on IgA for fighting mucosal infec- tion is that secretory IgA (S-IgA) and secretory IgM (S-IgM) are major components of the mucosal immune response. S-IgA has a well-documented role in prevention of viral infection by immune exclusion and under dimeric form ...

The determination of IgG avidity, after performing other tests (e.g., determination of IgG and IgM titers), in many cases allows confirmation or exclusion of active toxoplasmosis. Therefore, this test should be used in the diagnosis of the disease as a supplement to other diagnostic methods [...
Samples used for Dengue IgM/IgG RDT lab evaluation ✓ IgM RDT Evaluation Panel For the evaluation of the sensitivity and specificity, a set of 187 human serum samples was used as described inTable 2. For sensitivity, 50 MAC ELISA positive samples confirmed by PRNT were used. For specificity...
Despite being also highly sensitive and specific, PRNT testing does not distinguish between IgM or IgG antibodies in order to pose the diagnostics of recent or old ZIKV infection, contrary to the EDIII ELISA. The PRNT test is also expensive, labor intensive, and requires use of BSL3 lab ...

SARS-CoV-2, the virus that causes the COVID-19 disease, has been shown to cause immune suppression in certain individuals. This can manifest as a reduced ability of the host’s immune system to effectively control the infection. Studies have reported tha
