Introducing Rapid Tests to Measure IgM and IgG Antibodies to the SARS-CoV-2 Virus

SSI Diagnostica A/S is the exclusive distributor in the Nordics of antibody tests from CTK Biotech.

The tests are intended for the presumptive qualitative detection of IgM and IgG antibodies to the SARS-CoV-2 virus in patients suspected of a COVID-19 infection.

COVID-19 IgG/IgM Rapid Tests detects anti-SARS-CoV-2 IgG and IgM antibodies in human serum, plasma or whole blood.

The tests can be performed within 15 minutes without the use of time consuming laboratory equipment.

Simple One-step Test with Rapid Results*

  • Rapid results – read after 15 minutes
  • Easy to interpret results
  • No additional equipment or training needed
  • For human plasma, serum or whole blood

* See Instruction For Use for each specific product 

Performance of Antibody Tests

See how the three antibody tests performed in a recent evaluation conducted in Denmark.1

*Data adapted from: Evaluation of nine commercial SARS-CoV-2 immunoassays

When to Measure IgG/IgM Antibodies

IgM antibodies are generated initially by the body as a result of infection at about the time symptoms appear. 

The rapid test result depends on the time of infection.

IgM immune response is present after 5 days after infection, and will increase over time. Given that IgM is a marker of early infection.2

Highest IgG immune response is seen 14 days after infection.2

Determine Immunity with Rapid Antibody Tests

  • Determine seroprevalence in a given population
  • Define previous exposure

    This recent study from NOKLUS, the Norwegian Organization for Quality Improvement of Laboratory Examinations compared 17 SARS-CoV-2 antibody tests.

    Our partner, CTK Biotech, got placed in top three.

    The study from RUC compared six antibody rapid tests.
