On 5 October, the opportunity opened up for the public to book an antibody test in Västmanland under the auspices of the region.
A pent-up need appeared at first, which then declined.
In Sala, interest declined early and after a few weeks, times were scaled down so that staff would not be idle.
"No displacement effects"
When those in charge saw that the times were not right, they quickly re-prioritized, according to the region's medical chief of staff Åke Tenerz.
- We have brought in extra staff so it has not had displacement effects or competed with other tests, he says.
During October, November, December 2020, a total of approximately 8,000 antibody tests were performed.
These figures include healthcare staff in the region and the number may include the same people who have been tested several times.
Statistics for how many of all the samples taken on their own initiative by ordinary people can not be announced by the region when SVT asks.
13-14 percent positive tests
At present, the number of tests that have detected antibodies is 13-14 percent in Västmanland.
However, it is not possible to translate directly into immunity.
The region has issued a call that there is no need for an antibody test for those who have previously been found to be covid-19 positive.
In the clip, medical chief of staff Åke Tenerz reasons about the decision to invest in the antibody tests.
