COVID-19 is an infection caused by the SARS-CoV-2 coronavirus. COVID-19 causes upper respiratory symptoms that may include:
- Runny nose
- Shortness of breath
- Muscle or body aches
- Sore throat
- Loss of taste or smell
- Nausea or vomiting
- Nasal congestion
COVID-19 antibody testing is a blood test to determine if you’ve been infected with the SARS-CoV-2 coronavirus in the past. It does not indicate current infection.
When you have an infection, your body produces antibodies in response to that infection. It may take two to three weeks after infection for your body to build antibodies to a measurable level. Antibodies may remain in your system for several months after infection. Antibodies help prevent you from becoming re-infected after you’ve had an infection.
Antibody testing for COVID-19 may be indicated if:
- You had symptoms of COVID-19 in the past but weren’t tested
- You have an upcoming medical procedure scheduled
- You’ve had COVID-19 in the past and want to donate plasma
- Sick children who are suspected of having MIS-C (an inflammatory syndrome that occurs after a COVID-19 infection)
COVID-19 antibody testing is done by a lab blood draw. If you are interested in having this testing done, discuss with our healthcare providers if testing is right for you.
