What is a PCR test?

The PCR test (Polymerase Chain Reaction) allows the detection of a fragment of the genetic material of a pathogenic agent. A PCR test detects early and effectively in the early stages of the infection regardless of whether there are no symptoms or the individual is not going to develop them, as is the case with asymptomatic people.

To carry out the PCR test, a sample is collected from a nasal portion of the pharynx with a sterile rayon swab and will be subsequently analyzed in a microbiology laboratory.
