Test for coronavirus infection


A Test for Everyday Use

This is an in-vitro diagnostic rapid self-test for the qualitative detection of SARS-CoV-2 antigens. By taking a sample through a nasal swab, you can easily determine if you are infected with the virus that causes COVID-19.

The test is quick and reliable and gives you results in 15-30 minutes. Collect the test sample with a shallow swab in the nasal cavity with only minimal discomfort, regardless of whether you have symptoms or not, and wherever you are.

A Complete Test Kit

Each test kit consists of a nasal swab to take the sample, a test tube with buffer liquid to mix the sample with, a lid to seal it, and a test cartridge to reveal the results. The test also comes with detailed instructions in ten languages.

Test kits are available in three packaging sizes to suit different purposes, such as travel or quantitative testing. Read more about the products here: www.gibsonmedical.se/products

  • Rapid test for COVID-19
  • Recommended test method
  • Complement to PCR test
  • Minimal discomfort
  • Uncomplicated testing
  • High sensitivity and reliability
  • Results within 15-30 minutes
  • Meets EU standards

Usage and Quality

The test is performed by collecting a nasal swab sample which detects the presence of SARS-CoV-2, the virus that causes COVID-19, including its common mutations. The test has a high reliability, approximately 97% sensitivity (the probability of detecting infection in an infected patient) and over 99% specificity (the probability that a positive response is actually correct).

It is important to follow the instructions and to be aware that results may vary depending on the state of infection. You effectively monitor the risk of being contagious by applying a test on a regular basis, recommended every 2-3 days.

Test Results

Follow the authorities' recommendations regarding infection tracing in case of a positive result. Contact a health care provider if in doubt. Even a very faint line is considered as positive. Additional testing, for example a PCR test, may be required to confirm viral infection or to initiate infection tracing.

A negative result means the sample does not contain a sufficient amount of the virus, but infection cannot be completely ruled out. Always follow local and governmental recommendations and regulations.

Questions & answers

My PCR result deviates from my antigen test. How can that be?

In addition to sensitivity and specificity data that we answer in another question, there are a number of sources of error that can explain why PCR and antigen testing result in different outcomes.

  • A common reason is that the tests are not taken at the same time and we then recommend that you take a new antigen test as soon as possible after the PCR sampling to get a fair result.
  • Another source of error is that one does not see a very discreet positive line. Make sure you have good lighting and look very carefully after 15 minutes but also at 30 minutes at the slightest doubt.
  • As PCR sampling often takes place from three premises (eg throat, nose and saliva), it is currently being discussed whether it should perhaps be done with antigen testing also to increase sensitivity. It is not yet recommended by the manufacturer, which is partly due to the long processing time of European notified bodies to deviate from the instructions for use, but some countries are beginning to introduce this on a broad front: https://www.reuters.com/business/healthcare-pharmaceuticals/swab-throat -too-when-using-rapid-covid-test-israels-health-ministry-says-2022-01-10 /
  • PCR also detects non-infectious levels of virus while antigen testing is better at detecting high / contagious virus levels. This is the reason why PCR can be "false positive" up to 9 months after infection.

We always recommend that you follow recommendations from authorities, which in Sweden currently means that you test yourself with Rt-PCR for symptoms and isolate yourself while waiting for an answer (per 2022-01-10). Antigen testing offers a fast, cost-effective complement to this testing and is currently the best tool for general screening.

How reliable are your self-tests?

Our most popular test from New Gene is on the EU's list of trusted tests and all the tests we provide have over 90% sensitivity, which has also been confirmed in independent studies in the EU. It shows that the test for independent validation at the Paul-Ehrlich-Institut in Germany has shown 92.5% sensitivity at high (≤30) Ct values (low virus levels) and 100% sensitivity at low (≤25) Ct values (high virus levels)

If I take the test in the morning and then travel to work on public transport, could I not be contagious at work then?

Current scientific evidence suggests that virus levels need to be high for you to be contagious and it usually takes 1-5 days until virus levels are sufficiently high that you are contagious (and get a positive test result). Therefore, sampling every 2-3 days is recommended.

There is, however, a risk that your viral load increases to a contagious level throughout the day and that the test taken in the morning is a false negative (see response regarding reliability above). There is no available rapid test that can exclude contagiousness to 100%, so be sure to always follow guidelines issued by the authorities.

What should I do if I get a positive answer?

Follow the authorities' recommendations regarding infection tracing in case of a positive result. Contact your local healthcare provider or call 1177 (in Sweden) if you have questions.

What can I do if it is negative?

A negative result indicates that there is no virus in the sample, or that the virus load is below the detection limit for this product. The possibility of a virus infection cannot be completely ruled out though, and we recommend that you follow current guidelines from the authorities.

Is it possible to travel if you show a negative result from a self-test?

A travel certificate currently requires a healthcare provider to certify your test result. Different countries have different requirements for test methods. Many countries accept antigen tests, but some destinations require RT-PCR tests.

How does it work with mutations?

Conducted studies suggest the test performance is reliable when tested against most known mutations. Omicron has an increased number of mutations on the so-called spike protein (S-protein) compared to previous variants of the virus. However, not many mutations have been seen on the nucleocapsid protein (N-protein) which is decisive to discover an infection with the test. Our antigen tests are therefore expected to have maintained performance in detecting Omicron and other common variants.

If we test all staff every day, how big is the risk that we will still get someone with an infection?

It is not possible to give an exact figure, but the clinical data which is available suggest that if you have 100 infected people in the workforce, you will identify approximately 97 of these via correctly performed self-tests. Thus there is approximately a 3% risk of missing someone who is infected. However, testing should always be seen as a complement to other infection prevention measures and should not be regarded as a fool proof protection against infection.
