According to the United States Centers for Disease Control and Prevention, the antibody tests are not suitable for diagnosing an infection due to the fact that it takes up to three weeks for the body to make antibodies. , according to Koronavirus_info.
According to scientific studies, the concentration of antibodies to coronavirus in the blood of those who have been ill and vaccinated has a very indirect connection to the level of protection against the virus.
It is noted that at the moment experts do not know the required level of antibodies for effective protection against the virus.
Experts have denied the appropriateness of the antibody test, as the results of such testing are extremely unreliable and do not allow making convincing conclusions, especially regarding the level of human immune protection. A negative test does not necessarily mean that a person is healthy, and a positive test does not guarantee that they are sick.
As it was reported earlier, nearly a third of Ukrainians have immunity to coronavirus. 38-40% of Ukrainian citizens can have immunity considering numbers of vaccinated people.
