Triple COVID-19 Antibody Testing Device Indicates Prior SARS-CoV-2 Infection and If Your Vaccine Worked

A new seven-minute COVID-19 antibody testing device can tell you if you have had COVID-19 and if your vaccine worked.

Mantracourt Electronics Limited (Devon, UK) helped engineer the new COVID-19 triple antibody testing device which was designed by Attomarker Ltd. (Exeter, UK) and will tell people whether they have immunity against coronavirus and whether that immunity comes from developing antibodies after infection or the vaccine.


The Triple Antibody Test measures three types of antibodies: IgM – the first-responding antibody raised early in the infection; IgG – the long-lasting antibody, persisting in the blood for possibly six months; and IgA – the antibody released on surfaces of the nose and lungs as the first line of defense. These antibodies attack three different parts of the coronavirus: Nucleocapsid - the protein containing the RNA material inside the virus; Spike Protein – the protein that attaches to the surfaces of our cells when the virus invades; and RBD Protein – the part of the spike protein that docks to our cells leading to neutralizing antibodies.

The Triple Antibody Test tells you whether you have natural antibodies because you have had the infection before and which protect you against infection, or if you have vaccine antibodies to protect you against infection. The results appear in real-time and will be an evolving graph which at the end of the test shows the three antibody levels N, S, and RBD along with CRP. If the test reveals that you have antibodies above pre-pandemic levels, then you have some protection and if the results show that you have antibodies below pre-pandemic levels, then you may not have protection against the virus. The results can be downloaded straight to the Biomark App.

“We started off by building the device for Attomarker, but it quickly became apparent that there were other areas where we could assist to deliver the project such as machine validation testing,” explained Robert Badcock, managing director at Mantracourt. “We undertook pre-compliance testing and discovered the electronics and communication systems in the device could be improved. We designed a new power distribution module, new USB components and a USB hub, as well as replacing several of the specified cables in the unit. Overall, we managed to improve the kit while reducing around 60 per cent of the cost and also reduced noise, which is important from an EMC point of view.”
