Peter Kamp Busk, associate professor of medicinal biology at Roskilde University, says that there is a high risk of a false negative test result when a lightning test is performed.
– We know that the tests are better than that, so there must be something wrong somewhere in the system. The best explanation must be that you do not take the lightning test well enough, says the associate professor, who is, among other things, an expert in virus testing.
On the lightning tests is a control strip, which must give a color if the lightning test comes from humans, Busk explains.
– But if you do a test that is not far enough up in the nose, then it will only show that it comes from humans without being able to catch the virus.
– Those who are in charge of the test may not be equally careful every single time. Because if you have to do thousands of routine tests, it is difficult to concentrate on doing them all equally well, says Peter Kamp Busk.
