Debrief: what this case does and does not establish

Numeric thresholds and operating targets come from the current approved procedure. Do not treat a teaching example, dashboard number, or authority name as a universal operating setting.

A chemistry-class interference response covers every affected site and device: confirm the discordant result with an unaffected method, quarantine the affected device class, capture the record, search retrospectively, notify affected users, reconcile results, and document the event.

Use the current procedure for operating limits and apply the chemistry-class response across the whole affected fleet.
