Through the Omicron Neutralizing Antibody Screening, you can better understand if there is an immune response after vaccination, whether you may have previously been infected by Omicron BA.1 BA.2 & BA.4/BA.5, and/or have adequate protection antibodies including neutralizing antibodies against future infection.

1. What is antibody?

Antibodies are proteins produced by the immune system in response to an infection. There are Immunoglobulin M (IgM) and Immunoglobulin G (IgG). IgM is usually the first antibody produced by the immune system when a virus attacks. IgG is then produced for long-term protection. Therefore, positive IgM level usually indicates “currently infected” or “ recently infected”, while positive IgG level usually means “previously infected” or “attained immunity”.

Neutralizing antibodies refer to immunoglobulins that have the ability to reduce the infectivity of the virus by binding to a specific site to block the virus from entering and infecting human cells.

2. Who is this Antibody Screening suitable for?

This screening is suitable for individuals who want to evaluate their immune effect against COVID-19.

3. When should I have the antibody screening?

This screening should be conducted at least 14 days after the second dose of COVID-19 vaccine.

4. Suspect myself of having COVID-19, should I get the antibody screening now?

If you suspect yourself having COVID-19 or suffering from similar symptoms of COVID-19 include fever and shortness of breath etc., you are advised to do the COVID-19 rapid antigen test and seek medical advice promptly. In general, you can get the antibody screening 5 days after recovery.

Notes

  1. Serology Antibody Screening is NOT for any medical diagnosis nor treatment
  2. A positive serology antibody screening result does not preclude you from the infection of COVID-19.
