Much has been said about COVID-19 digital certificates during vaccination or COVID-19 tests whose results can also take a few minutes.
Now a new rapid blood test has emerged, which can confirm whether a person has already been immunized. Results are available in less than 5 minutes.
Do you need to travel and cannot confirm that you are already immunized? According to the information published in the Futurity, now there is a test that lets you know if a person has antibodies. The most interesting thing is the fact that the results are presented in less than 5 minutes.
The new COVID-19 antibody test is similar to the one used at home to determine blood type, where the user pricks a finger and places a drop of blood on a card. A fusion protein developed by the team detects whether there are antibodies that are produced by the immune system to provide immunity against future infections.
As noted, results are displayed in less than five minutes, faster than current lateral flow tests for detecting antibodies. These types of tests can be used to validate whether a person has been vaccinated.
See how the new COVID-19 test works…
According to the information, the investigators used 400 blood samples, half of which were from patients who had previously been infected with COVID-19. The test created identified antibodies in patients who were previously infected 87.5% of the time, a rate higher than ELISA tests performed in hospitals, which require hours.
