Since the beginning of the new coronavirus pandemic , the search for effective ways to prevent and detect Covid-19, a disease caused by the new coronavirus (SARS-Cov-2), has become a worldwide race. From varied tests to different vaccine options, laboratories and pharmaceutical companies have come a long way in order to improve these discoveries more and more.
Currently, an important step in preventing the disease is being able to confirm the action of the vaccine in the body, through tests that detect the antibodies responsible for fighting the virus in the human body.
SARS-Cov-2 is the virus that causes Covid-19.
In this sense, the Neutralizing Antibodies Exam (Rapid Antiprotein S Test) is an option that has been used to make this proof, both after the application of an immunizing agent and in cases of post-infection.
So in this article we are going to talk about how it is done and in which cases it can be done
What is the Neutralizing Antibodies Exam?
The Neutralizing Antibodies Test, or Anti-Protein S Antibodies Rapid Test, is a rapid test that aims to qualify the body’s immune response, assessing the ability of antibodies to block the action of the SARS-Cov-2 virus in the body of those who have already been infected or took an immunizer.
This viral action occurs due to the binding of protein S (Spike) to the receptor (protein ACE2) in human cells, but it is prevented when anti-protein S antibodies already exist. Thus, the virus does not replicate throughout the body, neutralizing the effects of the disease.
However, it is worth remembering that not every antibody test is able to detect their neutralizing function, which is why the Rapid Anti-Protein S Test is the most effective in this sense, since it is specific to protein S (Spike).
