Who can perform a COVID rapid test?
In principle, any adult can perform a rapid test. However, the Federal Office of Public Health (BAG) of Switzerland recommends that rapid tests be conducted by trained professionals. The test involves two phases: first, a thorough nasal and throat swab is taken, and then the swab is placed in a solution to determine the result. The error rate is high when performed by non-professionals, leading to potentially inaccurate results.
When should a COVID self-test be taken?
COVID self-tests are designed for individuals who want to quickly test themselves. You should neither have had contact with confirmed COVID-19 cases nor have any symptoms of COVID-19 infection when using a self-test. If you have symptoms, you should definitely be tested by professionals in a pharmacy, testing center, doctor’s office, or hospital. Also, do not use self-tests before visiting vulnerable individuals or medical facilities. The high error rate with self-testing can lead to false security and subsequent infections. The self-test generally provides a less accurate result than antigen rapid tests or PCR tests. Even if the result is negative, you should continue to follow hygiene guidelines, as it is possible to still be infected with COVID-19 despite a negative self-test result.
What should be done in case of a positive result?
If the self-test shows a positive result, it should be confirmed as quickly as possible with a PCR test. This must be conducted by a trained professional. If the PCR test also comes back positive, you must go into isolation. You should get detailed guidance from the professional administering the test. Specific regulations can also be found on the BAG website or by contacting the BAG hotline, where you can receive direct advice.
Can businesses purchase COVID rapid tests?
Yes, if you want to test yourself or your employees, you can order rapid tests through our online shop. However, you should have a trained professional in your company who can administer the tests properly.
Which COVID test should you buy?
Our range includes various self-tests:
Antigen rapid tests are usually purchased in packs of 25, although there are single-packaged versions as well. Each COVID test comes with detailed instructions explaining the application process.
Where can you buy COVID self-tests?
A self-test can be purchased at pharmacies, drugstores, and retail stores. You can also conveniently order the tests through our Swiss online shop, and we will deliver them directly to your door. However, when purchasing, we require your confirmation that the tests will be administered by a trained individual.
Types of COVID-19 tests
There are various methods and tests to detect an infection with the COVID-19 virus (often referred to as corona). Essentially, there is a distinction between antigen rapid tests and PCR tests. These primarily differ in the time it takes to obtain a result. With the rapid test, you can get a result within 15-30 minutes, but it is more of a snapshot.
Accuracy and procedure of PCR tests
A PCR test result can only be determined in a professionally equipped laboratory, and this process typically takes about 12-24 hours. The result can then be accessed online or delivered by email or phone. The PCR test is the most accurate method for determining a COVID-19 infection, which is why a positive antigen rapid test is usually followed up with a PCR test for confirmation.
Detection of past infections with antibody tests
Additionally, there is the antibody test, which only detects whether a person has been infected with the virus in the past. In such cases, antibodies have already formed in the body, which can be detected by this test. However, it is not possible to determine when the infection occurred, nor can it assess immunity to future infections. These tests are often used in studies to assess the population's exposure to the virus by testing large numbers of people to see what percentage has been previously infected.
How can you identify a high-quality test?
To identify a high-quality test, you should first check for certification. This ensures the test meets certain quality standards and provides reliable results. Tests without certification may be less trustworthy. High-quality tests have high sensitivity and specificity. Sensitivity measures how accurately the test detects positive cases, while specificity measures how accurately the test excludes negative cases. Tests with high sensitivity and specificity are generally more precise and reliable. Look for tests with CE marking and ISO certification, as these indicate the test complies with Swiss regulations and quality standards. Also, follow the manufacturer's instructions for storage and use to ensure accurate results. You can further assess the reliability of the test by checking independent studies and customer reviews for additional information on accuracy and performance.
Can I use a COVID rapid test even without symptoms?
Yes, you can buy and use a COVID self-test even if you have no symptoms. It’s important to note that asymptomatic individuals can still spread the virus. Therefore, regular testing is advisable to help prevent the virus's spread. Even if you show no symptoms, you could unknowingly transmit the virus to others, so it’s important to act responsibly and get tested. If you have contact with at-risk groups or frequently interact with others in your job, a rapid test is also beneficial even without symptoms. Regular testing can help slow the spread of the virus and potentially save lives. It’s important to be aware of your responsibility and contribute to the health and safety of everyone through regular testing. Keep in mind that a negative test does not guarantee complete safety, and caution is still needed. Even without a positive result, you should continue to follow recommended hygiene measures and practice social distancing. By acting responsibly, we can all contribute to slowing the spread of the virus and protecting the health of others.
When is a COVID rapid test recommended for private use?
A COVID rapid test for private use is recommended if you have symptoms such as cough, fever, or loss of taste and smell. In such cases, a rapid test can help you quickly determine if you are infected and take appropriate action to prevent spreading the virus. Even if you have been in contact with someone who tested positive, you should take a rapid test. Even without symptoms, you may be asymptomatic and still carry the virus. A rapid test can help detect an infection early and take steps to protect others. Before visiting elderly or immunocompromised individuals, a COVID rapid test can be a precaution to ensure you do not pose a risk to them. Similarly, a rapid test before travel or large events can enhance safety by preventing the virus's spread. It’s important to inform yourself about the correct use and interpretation of the test results before purchasing a COVID rapid test to ensure reliable testing.
Are all COVID-19 rapid tests suitable as health certificates?
There are various types of COVID-19 rapid tests, including antigen tests and PCR tests. Antigen tests provide quicker results but are less accurate than PCR tests. PCR tests are considered the gold standard for diagnosing COVID-19 but are more complex and time-consuming. If you require an official health certificate, you should check the specific requirements and accepted test types. Some countries or organizations may only accept certain types of tests or have specific requirements for test results. It’s important to note that a negative rapid test does not guarantee absolute protection against a COVID-19 infection. There is always a certain level of risk, especially if the test is not performed correctly or if the infection is still in its incubation period. Therefore, it is advisable to continue taking precautions, such as wearing a mask, maintaining social distance, and practicing regular hand hygiene. Stay informed about the latest developments and recommendations regarding COVID-19 to protect your health and the health of others.
