There are currently two different ways to carry out a corona test. A distinction is made between the PCR test and the rapid corona test. The way the two tests work is different. Many people are now asking themselves how the tests differ and how reliable they are. These questions will be answered here in a short summary.
The PCR test in comparison
Normally, a PCR test is carried out if corona is suspected. A swab is taken from the mouth, nose or throat and this can be used to check whether the virus's genetic material is present. The PCR test in question is very accurate , but in most cases takes more than 24 hours to produce the result. Furthermore, the PCR test also works when the patient is already healthy again and is probably no longer contagious.
How the Corona rapid test works
In addition to the PCR test, there are now also rapid corona tests . These do not examine the genetic material of the virus, but the virus proteins. These rapid tests look like pregnancy tests and are easy to use. They are particularly suitable for use outside the laboratory. As with the PCR test, the rapid test requires a sample from the nasopharynx. The sample is then placed in a liquid and then a few drops are added to the test kit. Finally, the liquid is poured over a test strip. A result is available after just 15 minutes . In contrast to the PCR test, this rapid test is somewhat less reliable, but the rapid tests can determine earlier whether someone is infected. The risk of infection is usually highest when there are no symptoms yet. The rapid test can be useful in the following situations : acute outbreak, acute illness, precautions for at-risk groups or precautions during school operations or events . When using rapid tests, it must be noted that if the test is negative, infection cannot be ruled out 100%. It simply indicates that the risk of infection is low on that day. A more reliable result is obtained when there is a high risk of infection.
All in all, you should always consult a doctor or the official hotline as soon as you have come into contact with an infected person or if you experience symptoms. In this sense: stay healthy!
Summary
What is the difference between the PCR test and the rapid test?
PCR test: result is only available after > 24 hours, very reliable, still effective after recovery, must be carried out by trained personnel
Rapid test: Results are available after 15 minutes, slightly less reliable in direct comparison to the PCR test, but provides certainty for the day, can be carried out at home
How reliable are the tests?
The longer the contact with an infected person, the more likely it is that you have been infected yourself. The statement is therefore much more reliable in this situation than for a person who has not had contact with an infected person. The test result must be interpreted in context.
Who will be tested?
Persons with symptoms, travelers returning from risk areas and other asymptomatic persons such as those from care facilities
Where can testing take place?
At general practices, hospitals and specially set up test centers such as at train stations or airports. ATTENTION: If you suspect anything, you should first contact your family doctor or the official hotline by phone to discuss what to do next.
