Clinical Utility
Solid Tumor Gene Fusion Analysis by Sequencing, Including NTRK detects gene fusions involving 18 genes. Another 18 genes are targeted by the panel for expression and/or mutation analysis.
Specimen and Container Info
Specimen Type: FFPE Block, unstained slides with matched H&E Slide
Processing and Submission Instructions
Formalin-fixed and paraffin-embedded tissue: Slides cut in the following order: 12 sections of 4μm unstained, 1 H&E, 10 sections of 10μm unstained, 1 H&E. Please take adequate precautions to prevent cross-contamination with other specimens during slide cutting and transport.
Transport Instructions
Transport to the laboratory at room temperature.
Stability Requirements

Room Temperature

FFPE Block, 5 years
Causes for Rejection

Specimens with less than 10% tumor content will be rejected. Do not submit decalcified specimens, cytology smears or samples from hematologic malignancies.
