On Oct. 1, 2024, the FDA began implementing a reorganization impacting many parts of the agency. We are in the process of updating FDA.gov content to reflect these changes.

In Vitro Diagnostics Emergency Use Authorizations (EUAs) - Serology and Other Adaptive Immune Response Tests for SARS-CoV-2

March 24, 2023 - The FDA has finalized two guidances: Transition Plan for Medical Devices That Fall Within Enforcement Policies Issued During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency and Transition Plan for Medical Devices Issued Emergency Use Authorizations (EUAs) Related to Coronavirus Disease 2019 (COVID-19). The guidances outline the FDA's general recommendations to transition from certain policies adopted and operations implemented during the COVID-19 pandemic to normal operations, including the FDA's recommendations for: 

  • Developing a transition implementation plan, 
  • Submitting a marketing submission, and 
  • Taking other actions with respect to these devices. 

The FDA encourages stakeholders to review the two final guidances, view the webinar, and reach out to the FDA if they have questions or concerns. In particular, for manufacturers planning to seek marketing authorization for their devices, the FDA recommends beginning work on a marketing submission, including a transition implementation plan, as described in the guidances.

On This Page:

Individual EUAs for Serology and Other Adaptive Immune Response Tests for SARS-CoV-2

This table includes information about authorized SARS-CoV-2 serology/antibody tests and other adaptive immune response tests that have been authorized individually. These EUAs have been issued for each individual test with certain conditions of authorization required of the manufacturer and authorized laboratories.

For additional performance information about EUA authorized serology/antibody tests, please see the EUA Authorized Serology Test Performance page.

For information on test EUAs that have been revoked see Historical Information about Device Emergency Use Authorizations: In Vitro Diagnostics (IVD).

In addition to COVID-19 tests issued EUAs, there are serology SARS-CoV-2 tests that have been authorized through traditional premarket review pathways.

To see additional authorization documents, such as letters granting EUA amendments or revisions, and a list of other brand names authorized under a specific EUA, select the plus (+) button beside the "Date EUA Issued or Last Updated" for each EUA.

Authorized devices in the table below are assigned the QKO product code.

Revision Concerning Viral Mutations

On September 23, 2021, the FDA revised the EUAs of certain molecular, antigen, and serology tests to establish additional Conditions of Authorization in response to the continued emergence of new variants of SARS-CoV-2. The revision requires test developers to update their authorized labeling and evaluate the impact of SARS-CoV-2 viral mutations on their test's performance as outlined in the letter. This revision is effective as of September 23, 2021 for all EUAs that are within the scope of the revision. This revision does not apply to EUAs for authorized IL-6 assays or standalone specimen collection devices and does not apply to EUAs that include substantially equivalent viral mutation conditions of authorization.


The FDA has determined that establishing additional conditions is necessary to mitigate the potential risk of false negative results due to either decreased sensitivity or non-reactivity associated with SARS-CoV-2 viral mutations. As set forth in the September 23, 2021 letter, developers of authorized tests that are within the scope of the revision are now required to routinely monitor emerging viral mutations and their potential impact on the performance of the authorized SARS-CoV-2 test(s).  If potential impacts are identified, the EUA holder must communicate with the FDA and end users about the potential risk that presence of the mutations may have on test performance. The EUA holder must also update their authorized labeling consistent with the revision letter and submit the labeling to the FDA within 3 months of September 23, 2021. By taking these steps, the FDA and the test developer can quickly act in response to the potential risks identified and, when applicable, share the findings on SARS-CoV-2 Viral Mutations: Impact on COVID-19 Tests. 

Viral Mutation Revision Letter – September 23, 2021

Umbrella EUA for Independently Validated Serology Tests for SARS-CoV-2

On April 28, 2020, FDA issued an umbrella EUA for SARS-CoV-2 Antibody Tests (Lateral flow or Enzyme-linked immunosorbent assay (ELISA) tests) that have been evaluated in an independent validation study performed at the National Institutes of Health's (NIH) National Cancer Institute (NCI), or by another government agency designated by the FDA, and are confirmed by the FDA to meet the criteria set forth in the Scope of Authorization of the EUA.  To date, however, no device has been added to the list of authorized devices in Appendix A of the letter of authorization.

On July 21, 2020, FDA determined, based on information and experience since issuing this EUA, that circumstances support revocation of this umbrella EUA so that FDA may issue individual EUAs. Individual EUAs will allow for broader indications and scopes of authorization, individualized conditions of authorization to address any issue unique to a specific test, and more streamlined EUA amendments, such as additional uses that would not fall under this umbrella EUA.

Accordingly, the EUA was revoked under Section 564(g)(2)(C) of the Federal Food, Drug, and Cosmetic (FD&C) Act.
