We meet annually at our scientific meeting and also offer training courses to educate students and individuals working in the arts of peripheral blood and bone marrow microscopical analysis, and in the
data interpretation of clinical pathology data.

This External Quality Assurance Scheme is available to all members of the ACCP who wish to compare their results when performing bone marrow smear evaluation and peripheral blood film analysis with other participants

Individuals are allocated a unique number in order to protect confidentiality.  Distribution of slides in CaseViewer will be at approximately one-two month intervals.


Participants are invited to review bone marrow or peripheral blood film images, and return the results for statistical analysis by the organisers. Results will be returned before the next distribution is issued and will include; individual performance identified using only the unique ID numbers, the consensus results and a statistical summary. It is expected that there will be a yearly report of the program at the annual ACCP meeting and furthermore this may be published.
