Existing tests use a nasal swab

New COVID-19 test “like a pregnancy test”

Three Walloon biotech companies have developed a serological test for coronavirus.   The test detects immune response against two specific COVID-19 markers.

The new test is similar to a pregnancy test and can tell you within a quarter of an hour if you are infected with coronavirus and have triggered a neutralising or potentially protective response in your immune system.

Coris BioConcept, Unisensor and Bio-X Diagnostics speak of a world first.  The new test allows antibodies against antigens NP and RBD to be identified separately. Antigens are substances that help in the production of antibodies.  Existing COVID-19 tests do not allow the antigens that trigger an immune response to be identified separately.
