Posted April 30, 2013

Dear CAP Accreditation Participant:

The CAP has further revised the checklist requirement ANP.22999 based on your feedback in response to the recent alert sent on February 15, 2013. The revised requirement allows for the reporting of results using either the manufacturer’s instructions or the ASCO/CAP scoring criteria. The revision below is effective immediately and will be published in the 2013 Anatomic Pathology checklist.

ANP.22999HER2 by IHC – ScoringPhase II
 If the laboratory interprets HER2 protein over-expression by immunohistochemistry (IHC), results are reported using either the manufacturer’s instructions or the ASCO/CAP scoring criteria.

NOTE: If the ASCO/CAP scoring criteria are used, the report includes the ASCO/CAP reference with the version number (e.g. year of publication).
