Container type
Collection Instructions Testing should be ordered only on surgical excision samples. Biopsy material is not appropriate. Blocks selected for MSI PCR testing must contain both tumor and normal tissue. If only tumor is present on the block, select an additional block with normal tissue

Areas of tumor must contain at least 50% tumor cells. The lab can remove adjacent non-tumor tissue, so the entire slide does not need 50% tumor cells, just the area with tumor. Contact the laboratory (415-514-1035, AGCLab@ucsf.edu) if the specimen suitability is uncertain. Label slides with pathology case number and block identification.

Complete an Applied Genomics Laboratory requisition and submit it with samples.

Sample type Formalin-fixed, paraffin-embedded tissue on three (3) unstained slides (5 microns thick) on charged glass. One adjacent hematoxylin and eosin stained (H&E) slide should also be included. Slides should be labeled with pathology case number and block identification.
