Covid-19 Antibody Test – How It Works?

The most confusing thing about coronavirus is that it affects different people in different ways. Sometimes you have symptoms while sometimes you have no symptoms at all. Therefore, the corona antibody test is the best way to find out whether you have previously been exposed to the coronavirus or not.

Two types of tests can determine whether or not you have developed antibodies to the virus. One is a laboratory test that requires a professionally trained healthcare professional to take a blood sample from a patient, which is then sent to a laboratory for conclusions.

How does the Covid-19 antibody test work?

Of the five main types of antibodies, the Covid-19 antibody test looks for two immunoglobulins, M (IgM) and (IgG). IgG antibodies are the most commonly found antibodies in our blood. They play an important role in increasing immunity against bacteria or viruses.

After initial exposure to the SARS-CoV-2 virus, IgM and IgG antibodies are usually produced between two and three weeks. However, it is not known how long these antibodies last in the blood.

A positive result can indicate that a person may have antibodies from a previous infection. You may even test positive if you have never had symptoms of the coronavirus due to asymptomatic infection.

However, a negative result indicates that the person has never been exposed to the coronavirus. And even so, whether the time of the test is too early to produce antibodies or under the detection limit of antibody tests.
