FFPE Sample Requirements

Arrow In this section
  • We require formalin fixed paraffin embedded (FFPE) material that has been reviewed by a histo/cyto-pathologist to identify areas containing tumour cells and determine suitability for testing.
  • Sections should be cut using a microtome and floated on the surface of a purified waterbath at 40+/-2°C. The sections should then be mounted onto glass slides and air dried (positively charged slides for FISH).
  • An H&E stained slide clearly marked with the areas of tumour to be examined should accompany all sections for FISH testing and for samples where it is required to enhance the neoplastic cell content to >20% for other services.
  • Please contact the laboratory for additional guidance or if you are unsure whether a sample is suitable
