2 minutes read2 minutes readIf you are travelling to China, it is now a requirement to have proof of two negative Covid-19 tests – a PCR swab test and an IgM antibody test – within 48 hours prior to flight departure. These control measures have been introduced to “reduce cross-border transmission of Covid-19 and protect the health and safety of passengers.” Find out more about how we can get you tested for your journey to China.
After a recent increase in infections from overseas, China has put in place new regulations surrounding the Covid-19 tests required before entering. Whilst many countries around the world already require proof of a negative PCR test on arrival, China also requires proof of a negative IgM antibody test.
The Chinese authorities state that “IgM antibody test results are stable, and the passengers’ test results can be a lot more accurate if the two tests are combined.” It is believed that “double negative” testing provides extra certainty as to whether a person has recently been infected with Covid-19, therefore lowering the transmission rate.
What is the difference between IgM and IgG antibodies?
The body produces IgM antibodies first in response to an infection. However, these antibodies typically decline after the infection passes, so testing for IgM antibodies can indicate a recent or current infection with Covid-19. On the other hand, IgG antibodies remain in the body for longer, providing an indication of the body’s long-term immune response to the virus.
