COVID-19 Testing in Carroll County

NEW! Sign up for testing at the Ag Center in Westminster using this testing form. A health care provider’s order is not required:

Testing Form / Registro de Pruebas

Once you complete and submit the form, our clinicians will enter it into the CRISP system, and you will receive a link to register for an appointment time. You should receive results in about 5 days.

The Ag Center test site is currently open Tuesdays and Thursdays from 1-4 pm and Sunday 10 am – 1 pm. It is located at 706 Agriculture Center Drive in Westminster.

Please note:

There will not be any testing on Sunday, August 9th. Testing is scheduled to return to the Ag Center on Tuesday, August 11th. 

*Due to the summer heat, effective Tuesday, July 14, 2020, and continuing every Tuesday, Thursday, and Sunday, the hours for the Ag Center Testing Site will change to 9 am – 12 pm.

Testing is an important part of controlling the spread of COVID-19. Testing for a current COVID-19 infection is available in many locations.

The Health Department’s testing site offers a diagnostic PCR test that shows if you have a current COVID-19 infection. These tests are highly accurate but may take a few days to get results. Rapid tests are available in a few locations, but may not be as accurate; if you test negative with a rapid test, you may need to retest with a PCR test to confirm. Antibody tests show if you were exposed to the virus in the past.

People who need tests for travel, work, school, or other activities should check to make sure what kind of test is acceptable. People who are getting tested because they may have been exposed to COVID-19 should be aware that it can take 2-14 days for an infection to develop, which is why you need to quarantine if exposed. A negative test does not mean you can stop taking precautions and end quarantine early.

Check with your health care provider’s office, pharmacy, or urgent care center to see if they offer testing.

If you have any questions or issues accessing testing, call our COVID-19 Call Center: 410-876-4848 Monday through Friday, from 8 AM – 5 PM.
