What is the difference between the BioSure Covid-19 Antibody Self-Test and other antibody rapid tests that are available?

Firstly, other antibody rapid tests that are available are not CE marked for self-testing. Secondly, there are two main different types of antibodies – nucleocapsid antibodies (which appear after an infection) and spike antibodies (which appear after an infection or vaccination) which are the neutralising IgG antibodies – the ones that are important for you to know your status about. Most antibody rapid tests, especially those manufactures in China, only detect the nucleocapsid antibodies which you do not produce from vaccination. Our BioSURE IgG Antibody Self Test detects the IgG spike antibodies that bind to the SARS-CoV-2 spike protein, which is the part that the virus uses to infect human cells. This is why they are called neutralising antibodies. The BioSURE COVID-19 IgG Antibody Self Test  holds more significance owing to the neutralising capabilities of IgG antibodies (as opposed to detecting antibodies to the Nucleocapsid protein).
