WHAT & WHY

Checks for genetic material produced by the virus (viral RNA) to determine if someone is currently infected.

Get active infection testing to find out:

If you have a current COVID-19 infection.

To meet testing requirements for school, work, or travel. Schedule appointment with as much lead time as your activity allows.

Key Feature

Know your antibody status

WHAT & WHY

Checks for spike protein antibodies to detect a prior or recent infection, regardless of whether sypmptoms were present.

Get antibody testing to find out:

If you had a prior or recent COVID-19 infection and now have antibodies.*

Your antibody level over time by using the same test from the same lab.*

*Note: Positive results may occur after COVID-19 vaccination, but the clinical significance is not yet known. It is not yet known how effective this test is at detecting antibodies in those that have been vaccinated. Additionally, how long antibodies remain detectable after infection or vaccination and how long protection, if any, may last is also not known. The results of this test should not be interpreted as an indication of degree of immunity or protection.

*Positive results with the antibody test may occur after COVID-19 vaccination, but the clinical significance is not yet known. 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.

Rapid antigen tests are less accurate than molecular tests, so your doctor may recommend a molecular test when your antigen test result does not make sense with your symptoms and exposure history. For example, when the antigen test says you are infected but you do not have symptoms (and have not been exposed recently). Another example is when your antigen test says you are not infected but you have symptoms. Rapid antigen tests have their best accuracy within 7 days of symptoms starting. Accuracy and the clinical significance of results beyond the 7 days is not known.

  • The molecular tests have been authorized only for the detection of nucleic acid from SARS-CoV-2, not for any other viruses or pathogens;
  • The antigen tests have been authorized only for the detection of proteins from SARS-CoV-2, and not for any other viruses or pathogens; and
  • All tests are only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of in vitro diagnostics for detection and/or diagnosis of COVID-19 under Section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner.
