Unlike the RT-PCR test, which detects the coronavirus in the nostrils.
The TROD test makes it possible to know if you have developed antibodies, and therefore you’ll know whether the cold you developed a few weeks ago was due to the coronavirus or not.
The TROD is a serological test that can detect the presence of antibodies (IgG) 14 days after coming into contact with the virus, while others laboratory tests also indicate the presence of IgM about a week after infection.
