Guidance on the Use of COVID-19 Antigen Test KitsNew York State has provided all school districts with antigen test kits. Each kit includes two tests. Outlined below is guidance about when an at-home COVID-19 test is recommended.
Test Yourself If...
|You have any COVID-19 symptoms||Test immediately.
A negative antigen test does not rule out COVID-19 infection. To best detect infection, a negative antigen test should be repeated at least 48 hours apart (known as serial testing). Sometimes a follow-up laboratory molecular-based test (PCR) may be recommended to confirm an antigen test result.
|You were exposed to someone with COVID-19||Test at least 5 days after your exposure.
If you test negative for COVID-19, consider testing again 1 to 2 days after your first test.
|You are going to an indoor event or a gathering||Test immediately before the gathering, or as close to the time of the event as possible.
This is especially important before gathering with individuals at risk of severe disease, older adults, those who are immunocompromised, or people who are not up to date on their COVID-19 vaccines, including children who cannot get vaccinated yet.
- Positive results from self-tests are highly reliable.
- Negative results from self-tests do not rule out SARS-CoV-2 infection. A negative self-test result may not be reliable, especially if you have symptoms associated with COVID-19.
- Invalid results from self-tests mean the test did not work properly, and a new test is needed to get an accurate result.
Should your child test positive from a self-administered antigen test, you should:
- immediately isolate them for 5 days from the positive test result or the onset of symptoms, whichever occurs first; and
- notify your child’s school.
If symptoms develop or worsen, contact your healthcare practitioner and seek additional care. Continue to wear a well-fitting mask around others for an additional 5 days following self-isolation.
