How to Report At-Home Tests to Primary.Health

  • Please report ALL kinds of at-home tests to Primary.Health every time your student takes one.
  • Here is the link to the portal:
  • You will need your child's access code.
    • Tip #1: Use the QR code and access code provided on the sticker on any home test kits provided by the school. Each student has a unique access code.
    • Tip #2: Take a photo of the sticker on a school-provided test kit for future use.
    • Tip #3: If you don't have a sticker, find your child's access code on Mark Day School's community portal:
      • Login to Mark Day School's online community portal.
      • Click on your child's name in the yellow navigation bar OR if you have more than one child at the school, click on the "Children" drop-down menu and then select your child's name.
      • Click on the "Contact Card" tab.
      • Look in General Information for your child's "Student ID." Your child's Student ID is their access code in Primary.
