Appendix number: 11-App-03
Parent procedure: Procedure 11 — Quality Assurance

Instructions

The Technical Manager and Quality Manager prepare this schedule annually. It is approved by the Laboratory Director and reviewed at management review. Update the schedule as rounds are completed and results received.
