About COVID-19 tests
The PCR test can detect minute amounts of genetic material in a sample. In this case, the PCR test detects if you are carrying SARS-CoV-2 virus genetic material. Ultimately, it is a diagnostic test to find out if you are carrying the virus.
It is a diagnostic test with the same reliability and sensitivity as a conventional PCR but with the significant advantage of receiving the results in only 35 minutes.
The rapid antigen test is a diagnostic method capable of detecting the proteins on the surface of the SARS-CoV-2 virus.
The sensitivity of antigen tests is somewhat lower than that of PCR tests.
The rapid antibody test is an immunoassay or serological test to determine whether you have antibodies against the SARS-CoV-2 virus (if you have had the disease).
The PCR test for travel is performed through a nasopharyngeal swab.
In the same way as the conventional PCR test, the rapid PCR test is performed through a nasopharyngeal swab.
In the same way as the PCR test, the rapid antigen test for travel is performed through a nasopharyngeal swab.
The rapid antibody test is performed by means of a fingertip puncture.
Avoid eating, drinking, smoking or brushing your teeth one hour before the COVID-19 test for travel.
