COVID-19 IgG Antibody Testing

This IgG Antibody Test isn't checking for the COVID-19 virus itself. Instead, it is looking to see whether your immune system has responded to the infection. If you have been exposed to the virus that causes COVID-19, your body typically produces IgG antibodies as part of the immune response to the virus.

COVID-19 IgG Antibody Testing

COVID-19 IgG antibody testing, also known as serology testing, checks for a type of antibody called immunoglobulin G (IgG). You could have had SARS-CoV-2 (COVID-19) and not know it. Not everyone who gets it has symptoms. COVID-19 IgG Antibody testing is for individuals who think they may have had COVID-19 and do not currently have symptoms.

How are people tested for COVID-19?

Two kinds of tests are currently available for COVID19: diagnostic tests and antibody tests.

  • A diagnostic test tells you if you have a current infection.
  • An antibody test tells you if you had a previous

What is this test?

This test is an antibody test. It will help assess if you have antibodies to the virus that causes COVID-19. An antibody test may not be able to show if you have a current infection, because it can take 1-3 weeks after infection to make antibodies.

What are the known and potential risks and benefits of the test?

Potential risks include:

  • Possible discomfort or other complications that can happen during blood collection.
  • Possible incorrect test result.

Potential benefits include:

  • The results, along with other information, can help you and your healthcare provider make informed recommendations about your care.

What does it mean if I have a positive test result?

If you have a positive test result, it is possible that you have or previously had COVID-19 and that you have developed an antibody response to the virus. Your healthcare provider will work with you to determine how best to care for you based on the test results along with other factors of your medical history, your symptoms, possible exposures, and geographic location of places you have recently traveled. There is also a chance that this test can give a positive result that is wrong (a false positive result).

Even a high-performing antibody test when used in a population without many cases of COVID-19 infection may produce as many or more false results as true results because the likelihood of finding someone who has been infected is very small. Your healthcare provider will work with you to determine the likelihood of false result.

It is not known how long antibodies to SARS-CoV-2 will remain present in the body after infection. It is not known whether having antibodies to SARS-CoV-2 will protect you from getting infected again or help reduce the severity or duration of a future COVID-19 infection

What does it mean if I have a negative test result?

A negative test result means that the antibodies to the virus that causes COVID-19 were not found in your sample. However, it is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID-19. A negative result may occur if you are tested early in your illness and your body hasn't had time to produce antibodies to infection. This means that you could possibly still have COVID-19 even though the test is negative. If this is the case, your healthcare provider will consider the test result together with all other aspects of your medical history (such as symptoms, possible exposures, and geographical location of places you have recently traveled) in deciding how to care for you.

It is important that you work with your healthcare provider to help you understand the next steps you should take.

Should you get tested?

This test may be right for you if you are not experiencing symptoms consistent with COVID-19. Information about COVID-19 symptoms can be found on the CDC website.

  • Have had or suspect you have had COVID-19, but have not experienced any new symptoms in the past 10 days (these symptoms include loss of smell or taste, difficulty breathing, feeling weak or lethargic, lightheadedness or dizziness, vomiting or diarrhea, slurred speech, and/or seizures).
  • Have not experienced a fever in the past 3 days.
  • Antibody tests may not show if you have been exposed to COVID-19. It can take your body at least two weeks after exposure to develop antibodies.

This test may NOT be right for you if you have any of the following concerns:
  • You are feeling sick or you have had a fever within the last 3 days
  • If you want to find out if you currently have COVID-19
  • You have tested positive for COVID-19 in the past 10 days
  • You have known exposure within the past two weeks
  • You have a weak or compromised immune system
