Preparation and notes

Collection instructions (preparation): Cut and send 5 tissue sections 5 µm thick from a paraffin-embedded block containing the tumor area selected for analysis: the selected area must be at least 1cm2 (per section) and tumor tissue must represent at least 70% of the cells; samples must be sent together with a serial section stained with hematoxylin and eosin with the selected tumor area marked. This information is crucial for the correct interpretation and integration of the results; if any of these criteria cannot be met, please contact the laboratory to assess the feasibility of the analysis before sectioning the samples.
