AMIS Reference Materials are made so a single laboratory can compare their results with 15 to 30 other laboratories. If your laboratory is reporting quality sample results that fail your accept/reject QA rules (or Westgard Rules), or if you have just woken up to a >10% QC sample failure; quickly follow the Control Sample Failure Checklist in the Technical Information Section.
Note: complaints about the performance of CRM’s are rare and always taken seriously. They are fully investigated in accordance with internal company procedures and in accordance with the AMIS ISO 9001:2008 Certification.
AMIS will immediately replace CRM’s found to be faulty or which have been mislabelled.
