This document provides a standardized procedure for laboratories to immediately report results that exceed critical thresholds, known as "panic values." When panic values are detected, the laboratory technician must confirm the result and inform inpatient nursing supervisors, physicians on duty, and document the notification. The person receiving the panic value must read back the result to confirm and state what immediate action will be taken, which is expected within 15 minutes. Timely notification of panic values helps ensure urgent medical intervention when needed.
