Seven of Sweden's 21 regional health authorities still do not offer coronavirus antibody tests to residents, according to a survey carried out by Nya Wermlands Tidning.
Antibody tests can determine whether someone has had coronavirus in the past, and as a result has a level of immunity.
They are useful to help people judge whether they are at risk of catching the virus again themselves, and as a result of unknowingly infecting others.
It is still unclear, however, exactly how much protection antibodies give or how long the protection lasts.
According to the Public Health Authority of Sweden, regional health authorities should prioritise PCR tests, which determine if someone is currently infected, with antibody tests a secondary priority.
These regions currently do not offer tests: Västerbotten, Jämtland Härjedalen, Dalarna, Blekinge, Värmland, Östergötland, and Gotland.
These regions offer tests (with slight variations in which age groups are eligible): Norrbotten, Gävleborg, Västmanland, Uppsala, Stockholm, Sörmland, Örebro, Västra Götaland, Jönköping, Halland, Kronoberg, Kalmar, Skåne.
Västernorrland will start offering tests from October 26th.
Some regions in Sweden that offer antibody tests are outsourcing the process to private healthcare companies such as Doktor.se, Capio, Werlabs, Doktor24 and Kry.
These and other companies also offer antibody tests, so if your regional health authority does not offer tests to residents, it is still possible to get tested if you are willing to pay more.
