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 blood test is a spike protein test which may detect antibodies from a prior COVID-19 infection or a vaccination, regardless of whether symptoms were present. A nucleocapsid protein test can only detect antibodies from a past 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.

The results of this semiquantitative test should not be interpreted as an indication of degree of immunity or protection from infection.

This test does not require fasting and is only available for persons 18 years of age or older.

This COVID-19 Antibody Test may be helpful if you:

• Have previously tested positive for COVID-19 or received a COVID-19 vaccination and want to know if you have detectable levels of IgG antibodies
• Were never diagnosed with COVID-19 and are looking to determine if you may have been previously infected with the virus

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
• Think you may have been exposed to COVID-19 in the past 14 days

This test can sometimes detect antibodies from other related coronaviruses you may have been exposed to, such as a virus that causes the common cold. This can cause a false positive result. Additionally, if you test too soon after infection or vaccination, your body may not have produced enough IgG antibodies to be detected by the test yet, which can lead to a false negative result.

This test may not be helpful if you have a compromised immune system or have a condition that makes it difficult to fight infections. If you are looking for other testing solutions,
