Dropping Off Your Sample

COVID-19 test drop box in Frick chemistry building

Where and when to drop off your sample

The daily deadline for dropping off your saliva sample in a drop box is 10:00 a.m., Monday through Friday. Samples submitted after that time will not be picked up and taken to the Lab that day. 

If you miss the 10:00 a.m. deadline on Friday, you can bring your sample in person to the testing clinic until 1 p.m. Any samples submitted after this time on Friday will be unable to be analyzed. 

The deadlines for samples below for undergraduates reflect testing times after Arrival Quarantine concludes and undergrads begin taking part in the regular asymptomatic testing process. Undergraduates, look to drop off your samples on the days associated with your residential college (meaning the college you were assigned to when you started at Princeton, regardless of where you are living currently). 

Undergraduates note: For sample deadlines and specific drop-off locations during Arrival Quarantine, refer to emails from covidtests@princeton.edu or uhscommhealth@princeton.edu.

  • Test-eligible employees on self-collection can submit on any day of the week, if you do so consistently (for example, every Monday). 
  • Some staff and academic departments have designated specific days for testing; if employees have not received notice from a supervisor/chair or from covidtests@princeton.edu about a designated day, faculty and staff can choose the most convenient day for them, Monday through Friday. 

Employees: If you will miss one of your designated testing dates for any reason (vacation, illness, not being on campus, etc.), please inform your supervisor.

If You Are On Campus Intermittently 

Many faculty, staff, researchers, and affiliates that are eligible for testing are not on campus every week. If your presence on campus varies from week to week, only come for testing during the weeks when you will already be on campus.

You can also time your testing for when you will already be on campus. If your schedule is that you are on campus on Mondays, you can come for testing on Mondays.
