Test Name: KRAS Mutation Analysis (NGS)
Methodology: Molecular Genetics
The KRAS Mutation Analysis (Solid Tumor FFPE) assay uses next-generation sequencing (NGS) technology to provide an assessment of the KRAS gene for the detection of genetic alterations within select regions of exons 2, 3, and 4 in human genomic DNA isolated from formalin-fixed paraffin-embedded (FFPE) tissue.
•FFPE tissue: Paraffin block is preferred. Alternatively, send 1 H&E slide plus 5-10 unstained slides cut at 5 or more microns. Please use positively-charged slides and 10% NBF fixative. Do not use zinc fixatives.
Storage and Transport
Use cold pack for transport, making sure cold pack is not in direct contact with specimen. Slides can be packed at room temperature.
Specimen Rejection Criteria
Turn Around Time (TAT): 24 hours
