Safer and More Detailed Answers About How Immune We Are: Now researchers at Linnaeus University in Kalmar are developing a new type of antibody test.
– You get an answer, not only yes or no if there are antibodies, but also what antibodies are present, to what extent these antibodies are present and how well they are bound to the virus, says one of the researchers, Ian Nicholls, professor of chemistry at Linnaeus University.

The researchers have collaborated with the bioassay company Attana by testing a new diagnostic platform that goes by the name of AVA (Attana Virus Analytics), the educational institution writes in a press release. With the help of the platform, they have managed to get a more nuanced picture of people’s immune systems – how it reacts to different types of viruses and bacteria. According to Ian Nicholls, it is also possible to obtain more detailed information on how an individual’s immune system reacts to the coronavirus in this case.
– In 15 minutes, you can basically get an answer if someone has antibodies, what the antibody profile looks like, and how strong those antibodies are.
The platform can also determine an individual’s immunity profile by comparing antibody samples taken at different times.
– Get a general picture of how antibody dependent immunity develops.
Need for evidence
Through the platform, the researchers connected a virus protein to then measure the interaction with the antibodies. The technology is currently being evaluated, and the test itself may be on the market sometime in 2021, Ian Nicholls hopes.
But the test is not intended to replace other tests, rather it should be viewed as an add-on, he says.
– There is a clear need for rapid and reliable tests for covid-19 antibodies. Society also needs access to more reliable test data that provides the opportunity to monitor antibody development.
