Enzywell SARS-CoV-2 IgA, IgM, and IgG

The Enzywell SARS-CoV-2 lgA, lgM, and lgG are immunoenzymatic methods for the qualitative determination of these antibodies to the SARS-CoV-2 virus in human serum.

Main benefits

Antibody Detection

Confirm current or past exposure to SARS-CoV-2 and access qualitative information that complements molecular studies.

Inactivated Native Agent

Inactivated native proteins are used to prepare diagnostic kits tested and validated at the INMI Spallanzani using samples obtained from COVID-19 patients.

One protocol

To improve lab throughput, easy automation, and reduced time to diagnosis, the three kits (IgA, IgM, and IgG) use the same test procedure and common reagents are interchangable between the three kits.
