Professor tells SvD, ”It’s unnecessary to test everyone who wants to be tested”

SvD has reported on increased waiting times in Stockholm and Skåne – which can run the risk of missing cases. According to the Karolinska University Hospital, responsible for coordinating testing in the Stockholm region, those who order a testing kit may have to wait five days. And for drive-in units, waiting times can total four to seven days

Karin Tegmark Wisell, Head of Department at Folkhälsomyndigheten, earlier told SvD about the importance of early-stage PCR testing.

– The highest probability of getting accurate testing results are seen in the first week of sickness. And the recommendation is taking the test before day four or five.

Other regions have decided to limit who can take a test. Control questions greet those living in Gävle, logging in to 1177.se to schedule an appointment. If you don’t have any relevant symptoms to COVID-19, like coughing or fever, you’re informed that you’re not allowed testing. The same is true if you’ve had symptoms for less than 48 hours.

– We manage sample taking from a socio-economic standpoint to reduce the regular care pressure, says Simon Nilsson, the Development Manager in Region Gävleborg.

According to the company Platform24, a subsidiary to the online doctor Doktor24, who runs the IT-platform for the region’s testing, around 22 percent of unnecessary testing are screened out in the process. This equals 9000 individuals in the area. Folkhälsomyndigheten reimburses regions with 750 SEK per test, which means that Gävleborg alone has saved 6,8 million SEK to screen out what is deemed as unnecessary tests.

Statistics from Folkhälsomyndigheten show that 520 000 PCR tests have been done in Sweden, most in regions that allow everyone to test themselves. This means that Folkhälsomyndigheten has reimbursed regions with about 390 million SEK so far.

Simon Nilsson doesn’t want to speculate on how many of these tests have been unnecessary. Still, he states that it’s reasonable to believe that regions will have some over-testing, without filtering who is eligible for testing.

Do you think there’s a risk that society spends an unnecessary amount of money on testing if you let anyone test themselves?

– Yes, I agree.

Simon Nilsson is supported by Anders Björkman, professor at Biomedicum at Karolinska Institutet in Solna.

– It’s doubtful to test everyone who, by varying reasons, wants to be tested. If one has symptoms of some kind that are consistent with a COVID-19 infection, it’s critical to test yourself. And it must happen fast, easily, and effectively, says Anders Björkman.

– But if one has just come into contact with another infected person, the value of testing is doubtful. The test results can then be negative and change to positive just a few days later. In these cases, quarantine is more critical. When the government pays for testing, it should be in value for society, to help fight the epidemic.

The ones responsible for Västra Götaland’s region disagree that the extra tests could be an unnecessary cost.

– We try to test anyone who shows symptoms. Our priority is to slow the spread of infection, says Kristine Rygge, Chief Physician and Medical Advisor in the Västra Götaland region.

Why isn’t it enough to test a smaller group, where you can see a real need for testing?

– Right now, we’re in the middle of a pandemic. Common cold symptoms can be COVID-19. Because it’s an illness that we contact trace, we must find as many infected as possible to protect risk groups and slow the spread of infection.

Not even the growing queues have made the region consider rationing the tests.

– We’re prioritizing that as many as possible should get the opportunity for testing because we need to slow the spread of infection. Longer response times are possible, but in most cases, you get an answer within three days, says Kristine Rygge.

Region Stockholm reasons in the same way. They state that it’s still possible to get a testing kit delivered home within 24 hours.

“The current widespread testing shows that Region Stockholm who has been hit hard by the pandemic, can follow the development of number of cases, which is crucial. Smittskydd Stockholm can contact trace each individual case and help slow the rate of spread,” says Maria Rotzén Östlund, Assistant Infection Control Doctor at Smittskydd Stockholm, in an email to SvD.

Region Stockholm asks everyone who wants to get a test to answer a series of questions about how they’re feeling through an app, but when SvD tests the app, you can order a test no matter what your answers are.

Kristine Rygge says that the region continuously reconsiders its strategy. If there would be a very high demand from individuals with common cold symptoms, all tests can be reconsidered.

– If we see a waiting time upwards a week, we have to rethink.
