COVID Testing

  • ETHS District 202 continues to partner with the University of Illinois (SHIELD) program to conduct COVID testing, which supports efforts to monitor and mitigate the spread of COVID-19 in the school community. Non-invasive testing for COVID-19 will be performed at ETHS and is free to all current students. ETHS will work to protect the privacy and confidentiality of students who participate in COVID testing.

    If a student is vaccinated and has not yet submitted proof, please complete the Proof of Covid Vaccination for Students as soon as possible.


    COVID Testing at ETHS

    Who: All students, regardless of vaccination status 

    When: Students will test during their PE/Wellness class. PE classes will be running with continued appropriate modifications per CDC, IDPH and Evanston Health Department guidance.  Please note that swimming classes are not running at this time. ETHS will make additional modifications in classes when students request this to their PE teacher.

    Where: On campus; staff will help direct students to their testing area

    What: SHIELD test - a free, non-invasive diagnostic test for the COVID-19 virus

    How:  Collecting a saliva (spit) deposit in less than five minutes, which provides results in 24-48 hours; students should not eat, drink, or chew gum 60 minutes before providing a saliva sample.

    Students will scan into the testing site using a QR code. The QR code should be saved on their Chromebook or phone.

      • The SHIELD QR code is available on the student’s Mobile ID Card. Students can access it by logging in to myETHS, clicking on their name in the upper right, clicking My Student ID, and scrolling down.


    Tips for Submitting a Successful Saliva (Spit) Test

    In the hour before the test:

    • Do not drink fluids (including water)
    • Do not eat
    • Do not brush or floss your teeth, or use mouthwash
    • Do not chew gum

    You may also want to rinse or gargle your mouth with water to remove any discoloration (such as from coffee) or small pieces of food. Be sure to do this at least one hour before your test. 

    At the test:

    • Pool your drool under your tongue with your face mask on.
    • Drool into your funnel and tube; keep your face mask on between spit deposits.
    • Slide the tip of your tongue along your gums behind your teeth to stimulate your salivary glands and deposit this saliva in the funnel.
    • Avoid swishing saliva in your mouth or pulling saliva from the back of your mouth.
