What is this test about?

“Antibodies” are part of the body’s immune response to infection or post-vaccination.

3mL of your blood will be drawn and the result can be ready on the same day.

Why do I need this test?

To determine your body’s antibody (immunity) level towards the COVID-19 virus or post-vaccination so you can stay protected.

What if your result positive?

You may test positive for antibodies even if you have never had symptoms of COVID-19. This can happen if you had an infection without symptoms, which is called asymptomatic infection.

You may also test positive for antibodies few weeks following COVID-19 vaccination. However, the presence of antibodies does not necessarily mean you are protected from future infection.

What if your result negative?

It could mean three things:

  1. You are not infected by COVID-19.
  2. or you have been infected by the virus very recently, but your body will take 2-4 weeks to develop antibodies.
  3. or your body may no longer have the antibody, even though you had a previous COVID-19 infection or vaccination.
