Which tests are available

There are several types of tests for novel coronaviruses. The test response provides only a snapshot, which is why it is important that you continue to comply with the infection prevention recommendations - even if your test result was negative.

Types of tests:

PCR tests

A PCR test – also called a molecular test – is a highly sensitive test that detects genetic material (RNA) of the virus using a lab technique called polymerase chain reaction (PCR). The test can also show if you are infected with a virus variant.

To take the test, a sample is collected from your throat by inserting a swab and gives the most reliable test results.

However, any test result is only a snapshot of your infection status at the time of testing, which is why it is essential that you continue to comply with the infection prevention recommendations even if your test result is negative. 

PCR testing should always be used if you:

  • Have symptoms of COVID-19
  • Are a close contact of someone who has tested positive for novel coronavirus
  • Have a positive antigen test
 

Antigen tests

An Antigen test – a rapid diagnostic test that can detect the presence of viral proteins (antigens) in a sample taken by a nasal swab. An antigen test (also known as a rapid (antigen) test) is a chemical test that detects viral proteins in a sample taken by a nasal swab. The rapid test is less sensitive than the PCR test and does not give an equally secure answer. However, you get your result back within 15 minutes and can help break the chains of infection faster. 

You should take a PCR test and not a rapid antigen test if you have symptoms or are a close contact of someone who has tested positive for novel coronavirus.

A rapid test, like the PCR test, is only a snapshot of your infection status at the time of testing.  Therefore, it is essential that you continue to comply with the infection prevention recommendations, even if your test result is negative.

What is a false positive test result?

Antigen tests can yield false positive test results. A false positive is when someone who does not have coronavirus tests positive for it. When there is a low prevalence of infection in society, and we use antigen tests on people who are at little risk of being infected – more people will get a false positive test result, and this could potentially make us think there are significantly more cases of COVID-19 than there really are.

 Therefore, if you are tested positive with an antigen test, you must have taken a follow-up PCR test as soon as possible, which will either confirm or deny the result of the antigen test. In this way, you avoid being in self-isolation for longer than necessary. At the same time, the PCR test can show if you are infected with a virus variant.

Please bear in my that any test result is only a snapshot of your infection status at the time of testing, which is why it is essential that you continue to comply with the infection prevention recommendations - even if your test result is negative. 

Antibody tests

Tests have been developed to detect antibodies against novel coronavirus in your blood. Antibodies are proteins that help fight off infections and can protect against getting that disease again (immunity). Unfortunately, we do not yet know to what extent the antibodies protect against new infection or for how long you are immune after you have recovered. Therefore, an antibody test cannot determine with any degree of certainty whether you can become infected again.

Antibody detection tests are not used in the public test system. The Danish healthcare system only tests for antibodies in connection with research and government monitoring. You can buy an antibody test, but the quality of these tests varies. We therefore recommend that you continue to comply with the general advice on how to prevent the spread of infection, even if an antibody test has shown that you have formed antibodies against novel coronavirus.

 

Test results

You get your test results on the digital platform 

 

sundhed.dk

 

If virus was identified in the test sample, your test results are positive and the Danish text will read either:

  • Positive (positive)
  • Formodet positiv (presumed positive)
  • Påvist (detected)

If virus was not identified in the test sample, the Danish text will read either:

  • Negativ (negative)
  • Ikke påvist (not detected)
