Virologist called the signs of a full recovery from coronavirus

A PCR test for covid-19 does not always give an accurate result, since the sample for this analysis is most often taken from the patient's nasopharynx, while the pathogen may already be located elsewhere in the body. Sergey Netesov, DOCTOR of Biological Sciences, Professor, HEAD of the Laboratory of Biotechnology and Virology at the Faculty of Natural Sciences of Novosibirsk State University, said this, Radio Sputnik reports.

“The fact is that a PCR sample taken from the nasopharynx determines the presence of the virus in the nasopharynx. As you know, the virus leaves the nasopharynx quite quickly: it can go into the lungs, into the blood, into the intestines, ”the expert specified.

According to the virologist, because of this, one negative PCR test result cannot be considered a 100% guarantee of recovery from coronavirus. To do this, it is necessary to repeat the analysis in two or three days or take blood for an additional study.

Also, the absence of coronavirus particles in the body can be confirmed by taking an antibody test, Netesov added.
