As vaccines continue to be distributed nationally, it is important that the population understands that herd immunity cannot be confirmed by vaccination rates alone.
What is a COVID-19 antibody test?
An antibody test allows you to check if you have antibodies to fight the virus. Clinical antibody testing can help a people know how protected they are and what antibody levels they might have. They choose to do this now because of the widespread virulent strains, some of which are thought to be significantly eluding antibodies and are less effective, and they know they are just as well protected after being vaccinated with COVID-19 vaccine.
How do vaccines work?
Vaccines contain inactive parts of the pathogen. When ingested, these inactive pathogen residues act as a trigger and cause your immune system to produce protective antibodies and T lymphocytes. Now your body recognizes the pathogen and is ready to fight for a strong impulse if it come across the same virus in future.
How Covid-19 Antibody Tests Work ?
The virus, like all living organisms, is partly made up of proteins.SARS-CoV-2, the virus that causes COVID-19, is made up of many proteins. When a person is infected, their immune system makes antibodies to many different proteins. However, many vaccines activate antibodies against a limited number of proteins. The vaccine is designed to generate antibodies only against spike protein, a key molecule found on the surface of the SARS-CoV-2 virus that helps the virus enter host cells and spread throughout the body.
When do I need to get an antibody test and why?
This is called a serological test and is usually done after complete recovery from COVID-19 or after vaccination.
Typically, a blood sample is taken by pricking a finger or by drawing blood from a vein. It is then tested for antibodies designed to fight the virus.
If the test is positive, it means that you have been infected with COVID-19 at some point in the past or have had some immunity, but there is insufficient evidence of antibodies, which means that you are protected from reinfection with COVID-19. The extent and duration of this immunity is unknown.
In a sense, antibody testing measures the level of protective immunity a person can have to test how well they are protected and to see if the vaccine actually works. works fine.
There is a significant advantage of accurate antibody testing where people who have recovered from COVID-19 can donate plasma antibodies to treat other seriously ill people and increase their resistance to the virus.
What are the different types of antibodies tests?
Covid Neutralizing Antibody Test - Neutralizing antibody levels predict immune protection against symptomatic SARS-CoV-2 infection. Neutralizing antibodies are key to protecting against future infections and provides accurate results. The neutralization test is a simple blood test and is relatively quick and easy to perform, but provides very specific information that can help determine safe procedures in the future and provide clarity. Monitoring can be used to better understand what levels of neutralizing antibodies are needed for protection and to help establish a schedule for the booster doses needed to maintain vaccine-induced immunity.
This Test detects neutralizing antibodies that prevent the COVID-19 virus from entering cells. It Shows positive in people vaccinated against COVID-19. It is Useful for Evaluation of vaccine efficacy and to Monitor neutralizing antibodies throughout life
Objective of Antibody test is to Assess the level of immunity in the community and Check your personal protection level for a comfortable journey.Blood Test at Home
Antibody Test for IgG - Detects IgG antibodies develop in most patients within 7-10 days after symptoms of COVID-19 infection or after vaccination. These antibodies indicate recent infection with COVID-19 and development of antibodies or successful vaccination against COVID-19.
When should I get my antibody level tested post vaccination?
It is recommended to go for this test after 2 weeks of your second dose of COVID vaccine to get accurate results.
