COVID-19 (SARS-CoV-2) Roche Elecsys Anti-SARS-CoV-2 S (SPIKE)

COVID-19 Antibody Test – Roche Elecsys® Anti-SARS-CoV-2 S (Spike)
Measure Your Immune Response to COVID-19

The COVID-19 Roche Elecsys® Anti-SARS-CoV-2 S (Spike) Antibody Test is a laboratory blood test designed to detect and quantify antibodies directed against the spike (S) protein of the SARS-CoV-2 virus, the virus responsible for COVID-19.

Using the internationally recognised Roche Elecsys® Anti-SARS-CoV-2 S assay, this test provides a highly accurate measurement of your antibody response following COVID-19 vaccination, previous infection, or both.

Whether you wish to assess your immune response after vaccination or understand whether you have developed antibodies following prior exposure, this test offers valuable insight into your body’s immune reaction to SARS-CoV-2.

What is the Roche Elecsys® Anti-SARS-CoV-2 S Test?

The Roche Elecsys® Anti-SARS-CoV-2 S assay is a highly sensitive and specific laboratory immunoassay that measures antibodies against the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein.

The spike protein is the primary target of most COVID-19 vaccines and plays a crucial role in viral entry into human cells.

This assay is widely used by healthcare providers, researchers, and laboratories worldwide to assess antibody responses following vaccination and infection.

What Does This Test Measure?

This test measures:

Total antibodies against the SARS-CoV-2 Spike (S) protein
Vaccine-induced antibody response
Antibodies developed following previous COVID-19 infection
Combined immune response from vaccination and infection

Results are reported quantitatively, allowing measurement of antibody levels rather than simply providing a positive or negative result.

Why Test for Spike Protein Antibodies?
Assess Vaccine Response

Determine whether your body has produced antibodies following COVID-19 vaccination.

Evaluate Previous Exposure

Identify whether you have developed antibodies following prior SARS-CoV-2 infection.

Quantitative Results

Receive an antibody measurement rather than a simple positive or negative result.

Monitor Immune Response

Track antibody levels over time if advised by your healthcare provider.

Peace of Mind

Gain additional information about your immune response following vaccination or infection.

Who Should Consider This Test?

This test may be suitable for individuals who:

Have received one or more COVID-19 vaccinations
Have previously tested positive for COVID-19
Suspect a past COVID-19 infection
Wish to assess their antibody response
Want to understand whether antibodies are present following vaccination
Require antibody testing for personal health monitoring
Understanding COVID-19 Antibodies

When the body encounters SARS-CoV-2 through infection or vaccination, the immune system produces antibodies targeting specific parts of the virus.

The Roche Elecsys® Anti-SARS-CoV-2 S assay detects antibodies directed against the spike protein, which is:

The primary target of most COVID-19 vaccines
Responsible for viral attachment to human cells
An important marker of immune system response

The presence of antibodies indicates that the immune system has responded to vaccination, infection, or both.

Benefits of the Roche Elecsys® Anti-SARS-CoV-2 S Assay
Highly Sensitive and Specific

What’s Included?

Your testing kit contains:

Blood collection device
Detailed sample collection instructions
Secure transport materials
Roche Elecsys® Anti-SARS-CoV-2 S laboratory analysis
Confidential online results report
Understanding Your Results
Positive Antibody Result

Antibodies against the SARS-CoV-2 spike protein were detected.

This suggests that your immune system has responded to COVID-19 vaccination, previous infection, or both.

Negative Antibody Result

No detectable spike protein antibodies were identified.

Possible reasons may include:

No prior vaccination or infection
Testing too soon after vaccination or infection
Antibody levels below the assay detection threshold
Quantitative Antibody Levels

Your report will include a measured antibody value that can help assess the strength of your detectable antibody response.

Results should always be interpreted alongside your vaccination history, previous infections, and clinical circumstances.

Frequently Asked Questions
Does this test detect antibodies from COVID-19 vaccination?

Yes. The Roche Elecsys® Anti-SARS-CoV-2 S assay specifically measures antibodies against the spike protein, which is the primary target of most COVID-19 vaccines.

Can this test determine if I am immune to COVID-19?

No. While antibodies are an important part of the immune response, there is currently no antibody level that guarantees protection from infection or disease.

Can I use this test to diagnose an active COVID-19 infection?

No. Antibody testing cannot diagnose current infection. Active infection requires viral testing, such as PCR or antigen testing.

How long after vaccination should I test?

Antibodies typically develop within several weeks following vaccination. Your healthcare provider can advise on appropriate timing.

Can antibody levels decrease over time?

Yes. Antibody concentrations may naturally decline over time after vaccination or infection while other components of immune memory remain present.
