The Public Health Agency of Sweden recommends that adults with symptoms of COVID-19 get tested to see if they have an ongoing infection. The same recommendation applies to children of school age and older, i.e., from about 6 years of age. Younger children of preschool age are primarily advised to stay at home if they are ill, without taking a test. The regions decide which people should be tested. There may be regional variations from the national recommendations, so you need to find out what applies in the region where you are.

Get tested if you have symptoms of COVID-19
The Public Health Agency of Sweden recommends that adults with symptoms of COVID-19 (in Swedish) get tested to see if they have an ongoing infection. The same recommendation applies to children of school age and older, i.e., from about 6 years of age. This applies even if you are vaccinated against COVID-19.
To avoid infecting others, it is important that you get tested to find out if you have COVID-19.
Visit the website www.1177.se/covid-19-prov (in Swedish) and select the region where you currently are to see what applies for testing there.
A test that shows if you have an ongoing infection should be taken no later than five days after you start to experience symptoms, because it is at the beginning of the illness that you have the greatest amount of virus in your body. While waiting for your test results, you need to stay at home and avoid close contact with others.
You do not need to get tested if the symptoms have a clear cause that you recognise, such as migraines or allergies.
If you have been vaccinated against COVID-19 in the past few days and experience symptoms that are common side effects after a vaccination you do not need to get tested if the symptoms disappear within 24 hours. Common side effects are tiredness, fever, chills, muscle pain, and headache. Stay at home as long as you have symptoms. If your symptoms persist for more than 24 hours you should get tested for COVID-19.
If you have had COVID-19 in the past half-year
If you have previously had COVID-19 in the past half-year and this was confirmed through a PCR test, an antigen test or an antibody test, you do not usually need to be retested for COVID-19, unless a doctor determines that you need to do so. However, you should stay at home as long as you have symptoms.
When you have recovered from COVID-19
If you are ill and have received a positive COVID-19 test result do not take another test to see if you have recovered. The tests are used to diagnose when you are ill and not to see if you have recovered or to assess whether you are infectious. Therefore, do not take a new test to see if you have recovered. It is the number of days that have passed since you fell ill and how long you have been free of symptoms that determine when you stop being infectious. You should stay at home and follow the rules of conduct that you receive from healthcare. Then you can go back to work, school or other activities.
Different tests – it is important that you take the right test at the right time
There are tests that can show if you have an ongoing infection right now, and tests that can show if you have already had COVID-19 and developed antibodies.

This is decided by your doctor.||No, unless a doctor determines that you need to take a second test.|
You take PCR and antigen tests while you are ill
The tests available to show ongoing COVID-19 infection are PCR tests and antigen tests. Both PCR tests and antigen tests are carried out while you are ill with symptoms of COVID-19, or if you are advised to get tested in connection with contact tracing. PCR tests are currently used on a large scale. A healthcare professional can administer the test, or you can take it by yourself through so-called self-sampling. The PCR test checks for the presence of genome parts from the virus that causes the infection.
An antigen test checks for the presence of protein parts of the virus. Sampling for antigen tests as well as the analysis of the test itself is carried out by healthcare professionals. The antigen test is not as sensitive as the PCR test but provides fast results. It can be used to confirm that you have COVID-19 but it cannot be used to exclude COVID-19. This means that if you have a negative test result, in some cases you may need to take another test.
You take an antibody test if you have previously been ill
An antibody test shows if you have previously had COVID-19 and developed antibodies. It takes time for the antibodies to form. Therefore, an antibody test is taken no sooner than about 2–3 weeks after you became ill. This means that you should not take an antibody test while you are ill with symptoms of COVID-19.
It is recommended that preschoolers stay at home without getting tested
Children of preschool age are primarily advised to stay at home if they are ill, without getting tested for COVID-19. Sometimes children aged 1–6 years have mild health issues that quickly pass and that are not signs of illness. In such instances, there is no need for the child to stay home from preschool or daycare. For example, a child may cough once or have a runny nose after spending time outdoors.
Find out what applies where you are
It is important to remember that the Public Health Agency of Sweden’s recommendations for testing apply nationally, but it is the regions that decide which people are tested. Among other things, this decision is based on the spread of COVID-19 and other infections in the region. You therefore need to find out what applies in the region where you are.
If you or your child share a household with someone who has tested positive for COVID-19, you may be advised by the health service to take a test even if you have no symptoms. In that case, you take the test as part of contact tracing.

What applies after I have taken the test?
While waiting for your test results, you need to stay at home and avoid close contact with others.

What is a PCR test and what is an antibody test? Tests for COVID-19
There are two different tests for COVID-19. Book a PCR test if you feel ill and believe that you have COVID-19. An antibody test can show you if you have previously had the disease.
Get tested if you have any symptoms of COVID-19
If you feel ill and have any symptoms of COVID-19 then book a PCR test. It’s important to get tested to know if you have COVID-19 so that you do not infect others.
