There are 2 tests available to see if you are infected at this moment:
1.Molecular test (PCR test) with a cotton swab in the nose.
PCR stands for Polymerase Chain reaction. In such a test, nasal mucus is taken and sent to a laboratory. The laboratory checks whether the coronavirus is present in the mucus and the result is known the following day in the evening.
The test only shows whether you have corona when the doctor takes the test. It does not show whether you have had corona before. This test costs 130 euros. Currently, most flight companies ask to present this test before boarding.
2. Antigen test with cotton swab in nose.
This rapid diagnostic test detects the presence of viral proteins (antigens) expressed by the COVID-19 virus in a sample of nasal mucus. The antigen(s) detected are expressed only when the virus is actively replicating; therefore this test is used to identify acute or early infection. The result will be ready in 1 hour and this test costs 40 euros.
A further 2 tests are available to see if you have had the covid infection and what your state of immunity is.
3. Serological test
This test shows whether there are antibodies for the new corona virus in your blood. For this, blood is taken to measure the amount of IGG and IGM values and is used to see if you have built up resistance to the virus. This test costs 40 euros per immunoglobulinic test.
4. Rapid test
Also for this test, blood is taken and checked whether you are positive for IGG and IGM. This test costs 40 euros and the results will be known the same day. If positive, it is recommended that you take the serological test to see how many antibodies you have. The reliability of this test is high. Be aware that there are many rapid tests on the market that are unreliable.
