Testing for COVID-19 infection among asymptomatic health care workers

For Whom

Health care workers (broadly defined as anyone working in a clinical, hospital or long-term care facility).

Please go to the following link and complete a volunteer interest form:

This information will help us understand who is eligible and the number of individuals with interest at a given facility so we can efficiently proceed with enrollment and screening administration. Note that we plan to conduct our research over the next 4 – 8 weeks so even if you do not hear from us immediately, it is possible that we will contact you in a few weeks to proceed with completion of a screening questionnaire. This is because we are only enrolling individuals without COVID-19 symptoms and to verify prospective participants are symptom free, we need to administer our screening questionnaire shortly before the SARS-CoV-2 test is administered.


We ask participants to provide a nasopharyngeal swab and then respond to symptom surveys for ~6 months. If symptoms develop we might ask you to provide an additional swab.


At or near healthcare facilities in the metro area.


We want to learn what proportion of health care workers are infected with SARS-CoV-2 but don’t have symptoms.

Frequently Asked Questions

Q: What if I test positive?
A: We will notify you as soon as we have the result. The result will be provided directly to you and not to anyone else including your supervisor. In the event of a positive test, we will make recommendations as to next steps but the decision as to how you proceed and if you should tell your immediate supervisor is entirely your own.

Q: What kind of SARS-CoV-2 screen will I receive?
A: A self-collected nasopharyngeal swab will be performed and the biospecimen will receive a ‘PCR’ test. This will tell us if you are currently infected with SARS-CoV-2, the virus that causes COVID-19. It is not any antibody test and does not inform if you were previously infected with SARS-CoV-2. This is a research-oriented screening study and the test is not diagnostic.

Q: Is this an antibody test and does it tell me if I was previously infected with SARS-CoV-2?
A: No.

Q: Is this the official CLIA approved CDC test?
A: No. Our test is for research purposes. While it is designed to be equivalent to the CDC test, results of our test cannot be used to make a formal diagnosis.

Q: How quickly will I get the results?
A: Results will be communicated to you in 4 – 8 weeks. The logistics of this study require that we run samples in large batches so we do not compete with the pipeline of tests for sick patients. However, having the test results will still inform you about whether or not you have been infected previously.
