Test information

Here you can read more about our tests



A qRT-PCR test detects the presence of virus in the mucosa and is the safest way to assess whether there is an active viral infection. The test is quantitative and measures the level of virus, unlike a qualitative test that only gives a positive or negative result. A qRT-PCR is the safest way to assess the presence of viruses. However, the test can not distinguish between infectious and non-infectious virus in the mucous membrane and can thus be positive from 2 days before the onset of symptoms up to about 3 weeks after a healed infection. If the test is positive, the rules are such that you are not allowed to travel.

A sampling stick with a cotton stopper is taken and inserted at the back of the nose to the posterior pharyngeal wall. There, the stick is rotated for about ten seconds against the mucous membrane. The sample is then sent encrypted to our partner's security laboratory and analyzed. You will receive an answer the day after (Regular time) or the same day (Express time). The certificate is signed by our licensed doctor and provided with a QR code so that it can be verified online worldwide. The certificate is very difficult to falsify. 

An RT-PCR is a laboratory analysis and takes about 3 hours to complete. 
Some rapid tests claim that they are based on RT-PCR, which is not the same thing. qRT means that the analysis is quantitative - ie the virus content is measured. RT-PCR can be qualitative - ie just answer the question: Is there a virus in the sample? Yes or no? RT stands for Reverse Transcriptas - ie by making exact mirror images of a specific part of the virus, you can identify if the virus is present in the sample through a special device - We use highly specialized equipment from American Roche. 


The result can be Negative, Positive or Non-analyzable. The prevalence of non-analyzable responses with us is less than 0.4%. If this happens, the laboratory will run the analysis free of charge the same evening. If the overtaking is not analyzable and this leads to a new sample having to be taken, it is also free of charge, but we are not responsible for additional costs that arise in such a situation.


The certificate is issued in English and contains the signature and stamp of a licensed physician. It is provided with QR code and is very difficult to counterfeit. Test results and Travel Certificates were sent out within 11-34 hours. The time depends on the type of service ordered (Regular or Express) and the time of day the test is taken. The absolute fastest test is Express (within 11 hours). The time when the test is taken is the time from which the validity period is calculated. 
Make sure you have at least a 6h margin from test response to departure. 



An antigen test is to detect the presence of a virus and is a method of detecting an ongoing infection with COVID-19.
The test is a quick test with a response of 15 minutes.  
An antigen test is an excellent screening test.
The antigen test we use is from American Abbott and has a very high specificity (> 99.8%). This means the probability of getting a negative answer if you do not have COVID-19 - ie a very low risk of false positive answers. A positive can be confirmed by a PCR as false positive responses may occur due to cross-reactivity with other viruses. At our clinics, we only test asymptomatic individuals. 
If you wish to test individuals with symptoms, contact our customer service by email and we will review the possibility of coming to you. The test meets the Swedish Public Health Agency's performance recommendations for antigen tests. 


The test result can be positive or negative. 
No level of virus levels is determined with this test. 


The certificate is issued in English and contains the signature and stamp of a licensed physician. It is provided with QR code and is very difficult to counterfeit. Test results and medical certificates were sent out immediately. Works only as a travel certificate to a few destinations. 



Fit to Fly is a simple health and functional examination that aims to investigate your need for assistance on the plane and whether your health condition makes it unsuitable for you to fly.
NOTE - this certificate is only required for special destinations - see swedenabroad.se for your destination. Parameters that are checked include the need for aids, mobility, blood pressure, heart, lungs, signs of infection, temp, etc. Note Bene! For pregnant women from the age of 28, a special certificate is required from an obstetrician or midwife who proves an uncomplicated simplex pregnancy (not twins). This can NOT be issued with us. In the event of pregnancy, documentation of the length of the pregnancy needs to be attached to your visit with us. 

A Fit fo Fly certificate can usually be up to 2 weeks old. See swedenabroad.se for your destination.


The certificate answers whether you are "Fit to Fly" or "Not Fit to Fly". If you do NOT get an approved examination, it can be due to several reasons. For example, temperatures from 37.5 Cº and higher can signal a virus infection - in such a case, one should wait for recovery.

It may also be that you are in a wheelchair. In such a case, you must contact the airline to investigate the possibility of assistance.


The certificate is issued in English and signed and stamped by a doctor. It is provided with a validation code and is very difficult to counterfeit.



An IgG / IgM antibody test can show if you have a recent or previous coronavirus infection. IgG - a so-called memory antibody, forms part of our immunity. If you have IgG, you have protection that probably lasts this season and can stay in risk groups accordingly The Swedish Public Health Agency. IgM, acute antibodies, indicate a recent infection. 

Quick tests are taken with a single stick in the finger. The blood is sucked up in a pipette and dropped into the test cassette together with reagent.

If you want to measure levels of antibodies in the blood, we assist with another referral Carlanderska Hospital for venous sampling via our partner Unilabs

Our sampler will explain what your answer means to you.

We use antibody tests from Healgen
The antibody tests meet the Swedish Public Health Agency's performance requirements for rapid tests. 

Rapid tests for antibodies are screening tests and a concentration determination of antibodies is always recommended in the event of a positive test result. 


Three lines can appear on the test - C-line (control line) which indicates that the test has been performed correctly. The IgM line (acute antibodies) and the IgG line (memory antibodies) 

  1. IgM negative, IgG negative - Indicates that there is no infection with Covid-19, or that there is not a high enough concentration of antibodies to produce a rash.
  2. IgM positive, IgG negative - Indicates an ongoing infection with Covid-19 day 3-5 to 10-14 after symptom onset. A new test is recommended in 14 days to confirm the presence of IgG. A positive IgM should be checked by PCR as infectivity may occur. 
  3. IgM positive, IgG positive - Indicates a recent infection with Covid-19 day 10-14 to day 21-35. Infectiousness is unlikely.
  4. IgM negative, IgG positive - Indicates a history of infection with Covid-19 after day 21-35. Infectiousness is unlikely. 

The test result must be interpreted together with your symptom picture in order to be able to give an overall assessment.
A more detailed description of the result is available on site.

Regardless of test results, it is of the utmost importance to follow the Public Health Agency's general advice and recommendations.

At present, it has not been determined what degree of protection a positive IgG response provides or how long any antibody protection lasts.

A positive answer must not lead you to stop following them protective measures which the Swedish Public Health Agency recommends to reduce the spread of infection.


IgM and IgG Antibodies

Both IgM and IgG are immunoglobulins produced by the immune system to provide protection against 2019-nCoV. Some patients with negative results in nucleic acid tests show a positive IgM test, which indicates that IgG / IgM detection is one of the effective methods for diagnosing 2019-nCoV.

The level of IgM antibodies begins to rise about a week after the individual is infected, while IgG production starts later than IgM (usually about 10-14 days after the onset of symptoms) and can last for 6 months or even several years, which means that IgG works as an indicator of previous infection. Patients suspected of being infected with 2019-nCoV can be quickly identified by simultaneous monitoring of IgM and IgG. During the outbreak period 2003-SARS and 2016-Zika, IgM / IgG antibody detection was used as one of the recommended diagnostic methods.

People with positive IgM should always be checked with a PCR test.

With us, there are routines to make your visit safe and hygienic.
