Access to Testing

We provide Centennial families access to PCR, Cue and Antigen testing through at home and school based testing. We also strongly recommend keeping a supply of tests at home. There are many ways you can get self-tests:

Order free self-tests from the federal government at Every home in the U.S. is eligible to have self-tests delivered without shipping fees. 

Order self-tests from Kaiser Permanente. If you're a member with a account, you can order 4 self-tests at a time to be delivered to your home, at no cost. If you don’t have a account, you can create one here.

Get no-cost self-tests at a Kaiser Permanente facility. You may be able to pick up self-tests in our pharmacies if you’re already planning a visit. We’re currently distributing iHealth and FlowFlex test brands.

Get no-cost self-tests from participating retail pharmacies. Medicare members can visit for participating pharmacies and present your Medicare ID card at the pharmacy counter. All other members can visit Costco, Rite Aid, and Walmart, and show your photo ID and Kaiser Permanente ID card at the pharmacy counter. Availability of tests may vary.

Buy self-tests outside Kaiser Permanente. These may be available online or at local retailers. You can submit a claim to get reimbursed for up to $12 per test, including shipping and sales tax.  

The shelf life of some brands of COVID-19 home antigen tests have been extended by the Food and Drug Administration (FDA). You can visit the following websites to see whether your test has been affected and view the new expiration date. The extension of the expiration date means that your test is still effective and reliable if you follow the manufacturer’s instructions.
