Total Antibody Against SARS-CoV-2 Spike Protein Test


Conform with government regulation* (designed for people who are vaccinated against covid-19)

COVID-19 pandemic is spreading around the world, and the current COVID-19 situation in Hong Kong is still very severe. There are still many cases of unknown origin, showing that the invisible transmission chain still exists. Countries are stepping up to vaccinate the people. A safe and effective COVID-19 vaccine can provide a certain degree of protection from infection, or minimizing the damage caused by the virus to health, is one of the most important measures to protect oneself and others and to ensure the sustainable operation of the Hong Kong medical system.

Whether one's body can produce effective antibodies after being vaccinated with COVID-19 vaccine?

COVID-19 vaccination produces antibodies which acts as protection and increase the immunity against the COVID-19 virus (SARS-CoV-2). However, the antibody level may differ from person to person.

PANGENIA launches Total Antibody Against SARS-CoV-2 Spike Protein Test, which accurately detects the level of antibodies in the blood through the principle of antibody antigen-specific binding.

This test could be applied to current available vaccine candidates, including SinoVac and BioNTech.
It is specially designed for people who are vaccinated against COVID-19 to confirm whether they can produce effective antibodies after vaccination. If the test result is positive, it indicates the antibody production is effective.
