According to US experts, antibody tests in serum against the SARS-CoV-2 virus do not indicate a person’s level of protection against the COVID-19 pandemic.
Antibody levels in the blood do not provide accurate information about whether a person is protected from COVID-19. In other words, having high levels of antibodies does not guarantee that you are immune to the SARS-CoV-2 virus.
That’s a Feb. 19 Forbes statement from Prof. Bruce Y. Lee, professor of health policy and management at the City University of New York (CUNY) School of Public Health.
According to Professor Li, the measurement of antibodies against the SARS-CoV-2 virus has become increasingly popular since the advent of a vaccine against COVID-19. In 2020, this test is the only way to know if you have some level of protection from COVID-19.

But as of December 2020, when vaccinations begin, the situation in the U.S. is not so simple. That has confused some about what the experiment means, and has created an opportunity for some to profit from the pandemic.
These tests, called serology tests, show antibody levels in human serum, which are very different from other types of humoral antibody tests, such as urine tests. or through a translator.
There are two types of serum antibody tests for SARS-CoV-2: qualitative tests, which tell you if you have antibodies in your blood, and quantitative tests, which provide antibody levels. The body is in the blood.
However, even if it is legal, you do not need to take this test. Because none of the above information tells you how protected you are from the COVID-19 pandemic.
