COVID-19 Vaccine Antibodies Test

Along with the implementation of the COVID[1]19 Vaccination Programme, many citizens wish to receive a safe and effective vaccine for personal and herd immunity, which is the key to bringing Hong Kong back to normalcy.

Are you wondering whether the vaccine is effective? Taking a COVID-19 Antibodies Test after getting vaccinated helps to evaluate the immune effect and ensure that the vaccine can effectively fight the virus.

Quality HealthCare is one of the local testing institutions (Laboratories in Group A) recognised by Hong Kong SAR Government to conduct COVID-19 Serology Antibody Test.
If you test positive for COVID-19 antibodies, a test report and result proof of a recognised serology antibody test will be issued. The result proof is valid for 3 months and can be used to fulfil the relevant requirement for shortened quarantine period for inbound travellers.

What is Neutralizing antibody (Nab)?

Under normal circumstances, the immune system will produce antibodies after the body has been invaded by a virus. Based on how they bind to the virus, such antibodies can be grouped under two different categories, namely binding antibodies and neutralising antibodies.

The general antibody tests available in the market can only test for IgG, in which the IgG responses indicate previous infection or body immunity. The antibody test launched by us can also detect neutralising antibodies. Produced by the immune system, neutralising antibodies are protective antibodies that can bind to the viruses and identify the cell locations, thereby reducing the virus' ability to infect. For evaluating the vaccine's effectiveness, monitoring of infection rates, herd immunity and protective immunity, and evaluating vaccine efficacy during clinical trials and after large-scale vaccination, it is necessary to test for the presence of neutralising antibodies.
