It’s bureaucratic ambiguity at its best —- all tests are initially developed (designed) in a lab, and most subsequent results are developed (determined) in a lab. The restriction on EUA approval applies to those tests that have not yet been submitted for EUA and are designed to be run (developed) in labs.
Tests that are designed to be Home use, Venue Screening, or Point Of Care are still eligible for EUA submission.
Apparently they believe they have enough lab tests approved.
