Additional Specimen Information
1. Unstained slides
Fine-needle aspirates, core biopsies and small/low-cellularity samples
a minimum of 10 unstained FFPE slides (5 micron sections)
Larger resections
a minimum of 6 unstained FFPE slides (5 micron sections)
2. An H&E slide clearly targeted by a histopathologist
Please include the tumour content assessed as this is an essential requirement for testing. Samples without a clearly marked target AND tumour % will not be processed.
The target for microdissection should contain at least 30% of viable tumour cells in a background of no more than 70% normal tissue content, including inflammatory cells - avoid including necrotic material in the targeted area. Slides are to be kept at room temperature at all times.
3. Each slide must be clearly labelled with at least two patient identifiers (e.g., name and block number, or NHI and block number).
4. Request forms must include the sample block number, any relevant clinical details and tumour diagnosis.
Specimens arriving with incomplete labelling/documentation or incorrect sample requirements will be rejected.
