Two boxes of COVID and flu tests can sit side by side on a shelf, come from the same manufacturer, and be legal for completely different users. One is a professional point-of-care kit. The other is an over-the-counter self-test. Buy the wrong one for the setting and either your staff cannot legally run it, or you paid clinic pricing for a test a school nurse could have bought by the case.
Here is the distinction, the rule that governs it, and how to order correctly for each program.
The rule: CLIA follows the specimen
The Clinical Laboratory Improvement Amendments (CLIA) apply to any facility that performs a test on a human specimen to diagnose, prevent, or treat disease or assess health. That includes a rapid antigen swab run at a front desk. If your facility performs even one such test, CLIA requires certification.
The simplest certificate is the Certificate of Waiver from CMS. It allows a facility to perform tests the FDA has categorized as waived, and only those tests, and only by following the manufacturer's instructions exactly as written. No modified sample types, no altered read times, no skipped controls.
Where OTC tests fit
An OTC self-test is designed for a person to collect their own sample, run the test, and read the result. When the person being tested does all three, CLIA does not come into play. When a staff member performs or interprets an OTC test for someone else, the facility is now performing a test on a human specimen, and CDC and CMS guidance is clear that the facility must hold a Certificate of Waiver and follow waived-testing requirements.
That single sentence decides most purchasing questions:
- School health office where the nurse swabs the student and reads the result: Certificate of Waiver required. Buy professional or CLIA-waived kits.
- Employer program that hands employees a self-test to use at home: No certificate needed. Buy OTC self-test kits.
- Physician office, urgent care, corrections intake, or public health clinic: Certificate of Waiver required, and the kit should be labeled CLIA-waived or for professional use.
- Shelter or harm reduction program distributing tests for self-use: OTC kits.
Reading the box
Manufacturers state the regulatory status on the packaging and package insert. Look for:
- "CLIA waived" or "For professional use" on point-of-care kits such as BinaxNOW COVID-19 Ag (professional, 40 tests) or Genbody COVID-19 rapid antigen (25 tests).
- "For self-testing" or "OTC" on consumer kits such as BinaxNOW self tests, Flowflex, GenaCheck, or Genabio 1- and 2-test boxes.
- Kit count and pack. Professional kits are usually 25 or 40 tests with shared reagents. Self-test kits are 1, 2, or 5 tests with everything individually packaged.
- Storage and dating. Rapid antigen tests have temperature limits and expiration dates. Ask your supplier for lot dating before a large seasonal buy.
What changed on January 1, 2026
CMS added newly FDA-categorized waived tests to the waived list effective January 1, 2026, and Medicare edits laboratory claims at the CLIA certificate level so payment goes only to facilities certified for the test's complexity. If you bill for testing, the certificate on file has to match the test you ran.
Ordering for respiratory season
- Confirm which certificate each site holds. Sites without a Certificate of Waiver get OTC kits only.
- Set a par per site by weekly test volume from last season, then add a four-week buffer for the peak.
- Standardize on one professional kit and one self-test kit per pathogen panel so training and reorder stay simple.
- Put the par on a standing order with a confirmed ship date so you are not chasing allocation in December.
Keystone stocks professional and self-test kits from Abbott, ACON, Genbody, GenaBio, and Healgen in Edina, quotes by the case or the pallet, and can hold a seasonal buffer for health systems under an open purchase order. Tell us the setting and the certificate and we will send the right kit.
