Sample rejection criteria

Requesting laboratories will be notified where samples are unsuitable for testing. Changes to the request form or new tissue section may be requested and testing will commence once the issue has been corrected. Patient material and requests will be returned to sites for correction if no communication to resolve is received.

The following issues will result in specimen rejection:

Request forms

• Illegible request. Our request forms are designed as editable PDF documents; we recommend that requesting laboratories complete forms electronically.
• Test(s) required not stated.
• Requesting laboratory not stated.
• Requesting laboratory/surgical slide/block number not stated.

Slides/blocks

• Number mismatch between slide/block and request form
• Slides/blocks without information.
• Insufficient material received or slides broken in transit.
