Immunoglobulin Tests – RESULTS WITHIN 24 HOURS!
These tests are designed to detect antibodies (IgM and IgG) that our immune system produces against the SARS-CoV-2 virus that causes COVID-19 disease. They are performed on blood samples collected by venipuncture. IgM antibody tests (Against Spike Protein or Nucleocapsid (N) Protein) and IgG antibody test may either be ordered together or separately.
IgM Antibody Test – Serology-Based Assay for Antiviral Immunoglobulin-M (IgM) Against SARS-CoV-2 Spike Protein and Nucleocapsid (N) Protein Tests
Serology-Based Assay for Antiviral Immunoglobulin-M (IgM) Against COVID-19
Accurate and Reliable Antiviral Immunoglobulin-M (IgM) Against COVID-19 Testing
The first antibody produced by the immune system during a viral infection is IgM. A positive IgM antibody test indicates that the virus may be present and that your body has started the immune response. When IgM is detected you may currently be infected, or you may have recently recovered from a COVID-19 infection. Our antiviral Immunoglobulin-M (IgM) antibody assay can accurately detect “acute” infection by looking at an individual’s immune response.
When to Test for Presence of IgM?
Typically, symptom onset starts around day five and the body will begin to develop IgM antibodies around 8 days post infection (compared to IgG antibodies, which develop around 14 days post infection).
Negative results to an IgM test do not rule out SARS-CoV-2 infection, especially for individuals who have been in contact with someone who was recently tested positive for COVID-19. Follow-up testing with a molecular diagnostic (RT-PCR test) should be considered to definitely rule out infection.
For never vaccinated person:
Testing positive for antibody against either N, S, or RBD indicates prior natural infection.
For vaccinated person:
Testing positive for antibody against the vaccine antigen target, such as the S protein, and negative for other antigens suggests that they have produced vaccine-induced antibody and that they were never infected with SARS-CoV-2.
Testing positive for any antibody other than the vaccine-induced antibody, such as the N protein, indicates resolving or resolved SARS-CoV-2 infection that could have occurred before or after vaccination.
IgG Antibody Test – Serology-Based Assay for Antiviral Immunoglobulin-G (IgG) Against COVID-19
Serology-Based Assay for Antiviral Immunoglobulin-G (IgG) Against COVID-19
Accurate and Reliable Antiviral Immunoglobulin-G (IgG) Against COVID-19 Testing
Antiviral Immunoglobulin-G (IgG) antibody test is very important for determining who has already been infected and might now have immunity to the COVID-19. Serological testing for SARS-CoV-2 is at an increased demand in order to better understand the number of positive cases of COVID-19, including for those who may be asymptomatic or have already recovered.
Why serological tests:
- To provide support in deciding as to whether people can return back to work.
- To determine who may qualify for a vaccination.
- To identify individuals who have recovered in order to see if they can donate plasma to treat people with severe forms of COVID-19.
High Medical Value Antibody Testing
Targeted Antibody Identification
It is important to target the right antibodies in order to identify an immune response against COVID-19:
- The SARS-CoV-2 IgG assay is designed to target antibodies against the coronavirus spike protein that can provide immunity. To identify an immune response against the SARS-CoV-2 coronavirus, it is important to target the RIGHT antibodies.
- Laboratory studies show that the SARS-CoV-2 IgG assay detects antibodies to the Receptor Binding Domain of the spike protein, which is important to provide immunity by neutralizing, meaning that these proteins are an effective way to measure your immune system function when compared to antibodies against other SARS-CoV-2 viral proteins.
