COVID Antibody Test: Why You Need It

As the COVID-19 pandemic continues to unfold, scientists are working hard to learn as much as possible about the virus that causes it. One area of intense focus is understanding how the body responds to infection with the virus. An antibody test with quantative results is a new type of test helping researchers gain important insights into how immunity works.

What Is An Antibody Test?

An antibody test is a blood test that can show if someone has had a previous infection with the COVID-19 virus. Antibodies are proteins the body's immune system produces in response to an infection. The presence of antibodies suggests that a person has been infected with a particular virus and has developed immunity.

The test involves taking a blood sample from a finger prick or vein in your arm and sending it to a lab for analysis. The results usually come back within a few days to a week. A positive result means you have antibodies and may have immunity to the coronavirus. A negative result means you haven't had the coronavirus or there weren't enough antibodies in your blood for the test to detect them.

It's important to note that antibody tests can produce false negatives - meaning you could have had the coronavirus but didn't have enough antibodies for the test to detect them. And false positives are also possible, especially if you have another type of infection or autoimmune disease.

Getting a positive result doesn't necessarily mean you're immune to COVID-19 and can stop taking precautions like wearing a mask and social distancing.

Who Should Get An Antibody Test?

Anyone who thinks they may have been infected with the COVID-19 virus should consider getting an antibody test. This includes people exposed to the virus but didn't have any symptoms. If you have been recently exposed to the virus, it may take a few days or even weeks for your body to produce enough antibodies to be detectable by the test. The Centers for Disease Control and Prevention (CDC) recommends waiting at least 7-21 days after your symptoms appear before getting tested so that antibodies will have had time to develop in your body.

People who have symptoms of COVID-19 should get tested for the virus itself rather than wait for antibody results. This is because the test can show if you currently have the infection and are contagious.

What Are The Benefits of Getting An Antibody Test?

You Can Determine If You're Immune

If you've already had COVID-19 and recovered, you may wonder if you're immune or could still get sick again. The only way to know for sure is to get a COVID antibody test. This test will show whether or not you have antibodies in your system that can fight off the virus. If you do have antibodies, it's likely that you're immune and won't get sick again even if you're exposed to the virus.

You Can Help Track the Spread of the Virus

By getting a COVID antibody test, you can help researchers track the spread of the virus. This information is important in understanding how immunity works and whether or not certain groups of people are more likely to get sick. This information can also help scientists develop new treatments and vaccines.

You Can Donate Plasma

If you test positive for antibodies, you may be able to donate plasma. This is because plasma from people who have had the virus is effective in helping other people who are sick with COVID-19. So, if you're looking for a way to fight this pandemic, this is one way to do it!

Help Researchers Learn More About The Virus

As our understanding of COVID-19 evolves, it becomes more and more important for researchers to access data from as many people as possible. By getting a COVID-19 antibody test, you will be contributing valuable data that could help researchers learn more about immunity, treatment options, and more.


Overall, getting an antibody test is a good way to protect yourself and others from COVID-19. It can help you understand your risk level and whether or not you need to take extra precautions in the future. If you think you may have already had the virus, an antibody test can also offer peace of mind by confirming your immunity status. So what are you waiting for? Get tested today!
