More than half of the fast tests for antibodies to COVID-19 were so poor that they should not be used.
This is according to the results of 17 commercial fast tests that have been investigated by the Noklus organization, writes Dagens Medisin.
Three of the tests received the rating of “good”, five were “acceptable”, while nine tests were rated “not acceptable”.
Senior Physician Mette Tollånes at Noklus believes that using the tests that fall into the “not acceptable” category must be avoided. All the tests in the survey are for professional use, not self-testing.
“Anyone can import and sell these types of tests if they are CE marked. We risk there being a lot of bad tests on the market if we don’t pay close attention”, she says.
The fast tests are designed to detect antibodies to COVID-19 in the blood so that you can tell if the test subject has previously been infected with the coronavirus.
Features that are considered are sensitivity, specificity, and ease of use. Specificity is the likelihood that those who do not have the disease will be classified as healthy. The greater the specificity, the lower the probability of a test result falsely stating that a person is ill.
