This Scheme assesses archival surgical stained sections, using Haematoxylin and Eosin staining methods employed during the use of “super” sized mega block tissue cassettes. The slide requested must be a true representation of that case, and a true representation of the quality performed in that centre as part of their routinely daily workload.

Staining Criteria Handbook available in Members' Area

Rationale

Super sized cassette systems or “mega blocks”, with dimensions of approximately 75 x 52 x 17 mm, are the equivalent size to 4 tissue cassettes routinely employed within histological practices. However, they have widely varying processing and cutting methodologies from day to day “routine” tissue blocks. Mega blocks are designed for processing and embedding larger, thicker specimens.

Submission

1 case of 1 H&E stained mega block slide from the date designated on the accompanying delivery letter issued with each assessment run.

Report
