In the present study, we compared the clinical performances of two IdyllaTM tests (the IdyllaTMKRAS Mutation Test and the IdyllaTMNRAS-BRAF Mutation Test) used in combination with an IVD kit (MEBGEN RASKETTM-B kit; Medical & Biological Laboratories Co., Tokyo, Japan) [15, 16] using FFPE tissue samples from colorectal cancer patients. This evidence concerns the gene BRAF and colorectal cancer.
