You are being given this Fact Sheet because your sample(s) will be tested for Antibodies to the virus that causes Coronavirus Disease COVID-19 - using the Elecsys Anti-SARS-CoV-2 S.

This Fact Sheet contains information to help you understand the benefits of using this test to evaluate your adaptive immune response to SARS-CoV-2, the virus that causes COVID-19.

What is the Elecsys Anti-SARS-CoV-2 S?

This test is an Antibody test. It will help assess if you have Antibodies to the virus that causes COVID-19. An Antibody test may not be able to show if you have a current infection, because it can take 1-3 weeks after infection to make Antibodies.

This test result should not be interpreted or mean that having any measurement of antibodies to SARS-CoV-2 will protect you from getting infected again. However, studies show that it will help reduce the severity or duration of a future COVID-19 infection, and most likely keep you out of hospital.

It is not known yet how long antibodies to SARS-CoV-2 will remain present in the body after infection.

What does it mean if I have a negative test result?

A negative test result means that antibodies to the virus that causes COVID-19 were not found in your sample. Additionally, a negative result may occur if you are tested early in your illness and your body hasn’t had time to produce antibodies to infection. This means that you could possibly still have COVID-19 even though the test is negative. If this is the case, your healthcare provider will consider the test result together with all other aspects of your medical history (such as symptoms, possible exposures, and geographical location of places you have recently traveled).

What does it mean if I have a positive test result?

If you have a positive test result, it is most possible that you have or previously had COVID-19 and that you have developed an Antibody response to the virus. A positive test result may also occur after receipt of a COVID-19 vaccine. Being part of a Herd immunity might also give a Positive test result.

0.8 IU/L is the cutline established between Negative and Positive Presence of Antibodies. Below are graphs showing the Level of immunity expected in the case of A-Z and Pfizer Vaccines in relevance of Age and time at one Vaccine, Two Vaccines, and one Vaccine after Positive Covid-19 Infection.
