Belgian professor Hermann Goossens warns that cold temperatures increase the risk of a self-test with a false positive result.
“Keep the self-test and perform the self-test at room temperature”, Recommended this Tuesday in the opinion columns of newspapers of the Mediahuis group that owns media outlets in Belgium, Luxembourg, the Netherlands and the Republic of Ireland.
The scientist, who led the testing team in Belgium until September, when all family members he invited to the Christmas party were tested “weak positive”, still outside, at 8 degrees Celsius. When they all repeated the tests in one at room temperature, and all the tests were negative.
“Watch out for false positive winter results. It’s a specific problem,” he wrote on Twitter.
