Non-colorectal GI tumors

Enhance diagnosis with advanced genetic analysis

Our next-generation sequencing assay for noncolorectal GI cancer assists in diagnosis, including variations in the most commonly mutated PDGFRA and KIT genes, along with NF1, BRAF, and other RAS genes. The test also includes detection of SETD2 and TP53 mutations, which have been shown to take on an aggressive clinical course.
