If 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.

China has introduced “double negative” testing in a bid to tackle infection rates from overseas

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.

Which tests can Better2Know provide for travelling to China?

Better2Know can provide fast, accurate results with the following home sample collection kits:

  • PCR Swab Test – Simply collect your combined nasal/throat swab at home and send it in the post to our laboratory for analysis.
  • IgG IgM Antibody Test – This test will provide separate results for IgG and IgM antibodies. It requires a finger-prick blood sample to be collected at home and sent to our laboratory.

All home sample collection kits include a comprehensive set of instructions which explain how to take your sample correctly. It is important to follow these instructions carefully to ensure the accuracy of your results.

Will I receive a certificate for my tests?

Once the laboratory has analysed your samples, Better2Know will email your results and certificates to you, prior to your flight. If there is any specific information that you require on your certificate, please let our booking team know in advance.
