How Swedish labs found a flaw in Covid-19 test kits – Radio Sweden | Sveriges Radio

It was when people with only mild or no symptoms began testing themselves for Covid-19 that the weakness of the BGI coronavirus test was discovered, according to Ola Winqvist, medical director at one of the labs that sounded the alarm over incorrect test results.

On Tuesday, the Public Health Agency announced that 3,700 people in Sweden had incorrectly been told that they had Covid-19. They had all used a BGI self-testing kit from China and had mild or no symptoms at all.
