Do you want to know if you are infected or if you have already passed the disease? In laboratories González They perform the COVID-19 test with their usual professionalism and rigor without having to travel outside of Dénia. Read on to better understand what the tests consist of and what they detect.
Detection depends on the days that the person has been in contact with the virus:
- Chronologically, the first thing that is detected in blood is the genetic material of the virus. This is done by testing the PCR, And is the most sensitive test with the fewest false negatives.
- 48 hours after infection, the quick test, which detects proteins from the virus capsule but is less reliable.
- Antibodies are detected from the fourth day. On days 7-8 they are detected IgG antibodieswho are the ones that give us immunity. The problem is that we don't know how long these antibodies last, or if they will protect us in the long term.
In the "window period", which is from day 1 to 4 of infection, we have no antibodies. Therefore, only virus tests (PCR) will be reliable, not antibody tests. Antibody tests are useful for monitoring patients and for conducting epidemiological studies at the population level. In patients with symptoms, the ideal would be to perform a viral detection test. The antibody test would help the person to know if the infection has passed and if there is natural immunity.
