The assumption of an infectious disease physician Olga Golubovska that the standard PCR test in a third of cases gives a false negative result, found confirmation in the West: according to doctors in several countries, the number of victims of coronavirus may have been strongly underestimated because the tests looking for specific antibodies in the blood, not infection-fighting T-cells in “memory” of blood.
About it writes Daily Mail.
It is reported that scientists have discovered that six of the eight men of those who lived with someone who had tested positive for COVID-19, showed negative results when tested for antibodies to the coronavirus in their blood.
But when the experts checked their blood samples for immunity T cells — part of a deep body’s defense against infections — they found that in fact these people moved COVID-19 with mild symptoms.
A recent study conducted at the hospital of the University of Strasbourg in France, studied seven families who had recorded unusual blood tests for coronavirus.
“Our results show that the epidemiological data based only on the detection of antibodies to SARS-CoV-2, can lead to significant underestimates of exposure, “says researcher Professor Samira Fafe-Kremer.
The immunological system of some patients, apparently “broken down” because of their reaction to the virus, so that those who do not have antibodies in the blood react to T-cells at a deeper level.
This is the conclusion reached by experts in immunology. This finding opens perspectives for new tests for coronavirus, which work to detect T cells similarly to tests for tuberculosis — possible for one lab to handle hundreds of patients to receive effective results within two days.
Currently, it is estimated that up to 10 percent of the population may have immunity to the virus — based on analysis of blood antibodies that detect the antibodies produced In the blood cells.
T-cells is the main weapon of the body — they stand out from white blood cells in the bone marrow, to kill viruses when the immune system needs additional support.
The above mentioned study involves a small sample and not yet reviewed, but is being carefully studied by immunologists.
Earlier, the “FACTS” wrote that the British newspaper the Guardian published an interesting article in which the forecast for the near future. We are talking about how the presence of antibodies in the human body will affect his social status, the freedom, the ability to get the job done.
