Four out of ten positive lightning tests last week were false positive


According to SSI, new weekly figures for tests must “give a more accurate picture of the spread of infection” in Denmark.

From now on, the Statens Serum Institut (SSI) will publish figures for confirmatory PCR tests every Friday.

It is when people have been given a lightning test and the same day or the day after is PCR-tested to get a double-checked result from the lightning test, which is considered more uncertain.

This is stated by SSI on its website. According to the institute, the figures should “give a more accurate picture of the spread of infection”. SSI recommends being tested by a PCR test if one has received a positive response from a lightning test.

The first of these figures was released on Friday. They show that 2170 people in Denmark last week were tested positive for coronavirus by a lightning test.

Of these, 91.9 percent were PCR-tested the same day or the day after to confirm or disprove the corona infection.

Among these, 1156 people were confirmed by a PCR test that they were infected. But 811 had received a false positive lightning test result and was still not infected.

This means that more than four out of ten positive lightning tests last week were false positive.

The figures also show that 1424 people who received a negative answer in a lightning test were still infected according to the PCR test. Conversely, 103,163 people were confirmed that the negative lightning test held true.
