COVID-19 Antibody Test
Antibodies are proteins that the body produces in response to an infection or vaccine. There are 2 types of COVID-19 antibody tests: a spike protein test and a nucleocapsid test.
This COVID-19 Antibody Test is a spike protein test which can detect antibodies from a prior or recent infection, regardless of whether symptoms were present. Positive results may also occur after a COVID-19 vaccination, but the clinical significance is not yet known, nor is it known how good this test is at detecting antibodies in those who have been vaccinated. Alternatively, a nucleocapsid test can only detect antibodies from a prior or recent infection.
This semiquantitative COVID-19 Antibody Test provides a positive or negative result and a numerical value that can show your immune response over time if you use the same test.
This COVID-19 Antibody Test may be helpful if you:
Have previously tested positive for COVID-19 or were never diagnosed with COVID-19 and are looking to determine if you may have been previously infected with the virus
Want to know if you have detectable levels of COVID-19 antibodies
Want to track antibody levels over time
This COVID-19 Antibody Test may not be helpful if you have a compromised immune system or have a condition that makes it difficult to fight infections.
You should not get this COVID-19 Antibody Test and instead contact your healthcare provider if you are feeling sick or have had a fever within the last 72 hours, think you are currently infected with COVID-19, were diagnosed with COVID-19 in the past 10 days or think you may have been exposed to COVID-19 in the past 14 days.
How long antibodies remain detectable after infection or vaccination and how long protection, if any, may last is not yet known. The results of this test should not be interpreted as an indication of degree of immunity or protection.
