COVID-19 Antibodies Test Kits

Testing performed through traditional blood draw or dried blood format to detect the presence of antibodies from natural exposure to coronavirus or vaccination.

Your Immunity Pathway


If you’ve been recently vaccinated against COVID-19, that’s a significant first step accomplished!

A post-vaccination antibodies test sets you on a path forward to reduce your anxiety and concerns about your level of resistance against the SARS-CoV-2 virus causing COVID-19

Safely Re-Engage in Life

Answering these four questions and getting a positive response will enable you to reclaim more confidently your social freedoms and safely re-engage in life because of your immunity against COVID-19.

Was my antibody response optimal?

Let’s get tested.

Some people’s immune system do not respond well to vaccinations, especially those who are more elderly or immunocompromised

Do I have enough antibodies?

Let’s do a count.

Although you might find antibodies, it’s critical to make sure there is a high quantity of immunoglobulins in your body.

Are my antibodies effective against SARS-CoV-2 virus?

Let’s test its strength.

Lab testing can confirm the binding strength or ‘avidity’ of your antibodies to the virus which increases its effectiveness in attacking it

Will my antibodies work against the new variant strains?

Let’s test its specificity.

Neutralization testing will determine if your antibodies can specifically prevent new variant strains.

And if you discover that your immunity response is sub-optimal or not strong against some variants, that’s manageable because you now know your risks. Continue to wear your mask and maintain social distance until you can get a booster. Your physician will be able to best advise you on next steps.

We can answer all of the above questions with a
Self-Test for COVID-19 Antibodies

Second Generation Antibodies Testing

Using a small blood sample, this post-vaccination antibody laboratory-based test helps determine if your immune system has developed antibodies after natural infection or vaccination against the SARS-CoV-2 virus spike protein.

You can perform this test yourself using a self-test kit to collect a few drops of blood and send it to the laboratory for processing.

Our laboratory partner is located in British Columbia and is fully accredited to perform this antibody test. This test has been shown to be equally sensitive and reliable when compared to a standard blood test.

COVID-19 Antibodies Self-Test

Why use our COVID-19 antibodies test?

  • Gold Standard for Testing immunity
  • Correlates well with T-cell immunity
  • Virus Neutralization Test (VNT) the way to test Antibody measure
  • Other commercial tests correlate poorly to VNT and only measure Wild-type virus immunity

What do you get out of it?

  • The ability to follow your own immunity to present and future variants
  • Understanding if and when you need a booster shot
  • Knowing how protected you are while travelling
  • Knowing your immunity when a vaccine escape variant presents

Self-Test Blood Spot Collection

What’s involved?


Order and receive your at-home test kit


Collect and ship your samples to the lab


Get results in the Immunity Passport App

Your kit will contain all the necessary supplies for self-collection in the comfort of your own home. The test only requires you to fill 5 circles with 2 drops of blood in each circle. You will collect your blood sample using the paper blot included in your kit.



How the Antibodies Self-Test Kit Works

Effective antibodies need to do two things

Your lab test will determine if your antibodies can neutralize the various strains of COVID-19 viruses.

Anatomy of the SARS-CoV-2 Virus

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). The novel coronavirus now known as the SARS-CoV-2 is a new strain which has not previously been identified in humans.
The core protein of SARS-CoV-2 is the N protein (Nucleocapsid protein), which is a protein component located inside the virus and is often used as a tool for diagnosis of coronaviruses.


From a naturally acquired COVID-19 infection from the community, our immune system develops antibodies against both the spike protein (S-protein) and nucleocapsid protein (N-protein) portions of the virus.

In Wave 1 and Wave 2 of the pandemic, most laboratory and rapid cartridge antibodies testing platforms focused on detecting recent natural infection by identifying antibodies against the less mutagenic N-protein.

In contrast, COVID-19 vaccines contain only some components of the S-protein to stimulate an antibody response.

To detect antibodies triggered by vaccination, we identify antibodies against the COVID-19 S-protein.

An immune response can be detected a few days or weeks after individuals have been infected by or received a vaccine against COVID-19.

Presently, the 2020/21 COVID-19 vaccines appear to offer some immunity against the  wild type and some newer SARS-CoV-2 variant strains first discovered in the UK (B.1.1.7), in Brazail (P.1) and South Africa (B.1.351).

Studies of vaccine efficacy show antibodies being present soon after the first vaccine dose. The second shot serves as a booster for the body to continue to mount an antibody response.

Today, we cannot conclude that long-term immunity against COVID-19 exists after one round of vaccinations. As variant strains evolve, we will likely need additional vaccinations against new strains to minimize the risk of getting sick again.

The presence and later absence of antibodies may not mean that all immunity has been lost as there is evidence that our body’s immune system has a ‘memory’ of antibodies against strains we’ve been infected with or exposed to via vaccination.
