SPECIMEN MANAGEMENT MEANS…
Policies, procedures and infrastructure to support
the safe handling and treatment of biological
specimens

PITFALLS Saying “Yes” to everything
Accepting every specimen
Afraid to say “No” to physicians Someone with sufficient authority MUST
support laboratory policy Good lab practice – Patients first!
Having no boundaries for technical issues
