The information in this section relates to the testing program for individuals at Princeton who are not exhibiting symptoms consistent with COVID-19. If you are experiencing symptoms related to COVID-19, please visit this University Health Services webpage for information on symptomatic testing.

Princeton’s asymptomatic testing protocol is designed to screen our University population and to identify positive cases at early stages to ensure that they are isolated to prevent community transmission. The protocol includes testing at regular intervals for Princeton University undergraduate and graduate students, faculty, staff, and researchers who are on-campus and meet certain criteria.

Individuals should not take part in the asymptomatic testing protocol if they are ill. Also, we do not have a process for expediting individual results, and we cannot guarantee results on a specific timeline.

For important information about the test and how the University may use or disclose your personal information, please read “Informed Consent for COVID-19 Testing (PDF).” Individuals participating in the asymptomatic testing protocol are required to agree to the terms of the consent prior to participation.


Students participating in the asymptomatic testing program must continue to do so until further notice, regardless of vaccination status. As of July 6, 2021, all fully vaccinated students will be tested once weekly, and students not yet fully vaccinated will continue to test twice weekly. Fully vaccinated means that you have received a final dose of approved COVID vaccine more than 14 days ago AND have uploaded evidence of vaccination status to MyUHS and had that evidence verified.


As of July 6, 2021, fully vaccinated employees verified through VacStatus and active on campus will be tested once weekly.

Also as of July 6, 2021, employees who are not yet fully vaccinated (as captured in VacStatus) and who are working on campus must be tested twice weekly.

The University may, at its discretion, adjust testing frequency in response to public health conditions on campus or the local area.

Type of test being used by Princeton

Our asymptomatic protocol uses a diagnostic test, also known as an RT-PCR test, which allows for detection of the virus’s genetic material in the sample a test participant provides. Unlike antigen tests, a confirmatory test is not required for RT-PCR tests. For more information about the different types of COVID-19 tests, see this FDA webpage.
