How To Check If You Have Covid-19 Antibody?
Antibody testing is becoming popular in India with the second wave of the Covid-19 epidemic because many people suspect that the virus has spread or are interested in measuring its values after vaccination.
In addition, numerous laboratories advertise their antibody testing at various costs, stating that in future they will signal “protection” or “immunity” against the virus.
How antibodies function and how they are assessed?
The first antibody created when the immune system takes action is ‘IgM’ when a person gets infected. These are started around a week after infection, reach peak levels at three weeks, then decrease extremely rapidly, and ‘IgG’ antibody start to develop. These are the most significant protective antibodies, particularly in the long run. These antibodies grow from 4 to 8 weeks after infection. They then decrease rather slowly.
IgM and IgG are ‘binding’ antibodies that physically link their y-structure to the viral protein, flag and cause it to be destroyed by macrophage cells. They can also attract naturally occurring killer cells and destroy virus-infected cells. They are simply markers and cannot interfere with virus infection.
A subset dubbed “neutralising” anticorps can impact the capacity of the virus to infect cells by avoiding the structural modifications essential for entry into a host cell. Infection protection takes the form of viral infection blockage and/or replication.
For Covid-19, it is not known which antibodies defend from the virus at the time, and how far, but scientists think that antibodies are likely to be neutralised. Most neutralising anticuerpos are IgG.
Today, antibody testing in the market shows IgM or IgG antibodies, and sometimes IgA, created after IgM and playing a major part in the protection of the body’s mucous membranes. These anticorps, in turn, show prior exposure or immune response following vaccination. These assays quantify binding antibodies and are used to quantify exposure in serosurveys.
One can simply check if they had been infected with COVID-19 in the past or not by taking Antibody tests. One can also find the number of antibodies present in the body by getting the test mentioned below:
