The cobas® KRAS Mutation Test, for use with the cobas® 4800 System, is a real-time PCR test for the detection of seven somatic mutations in codons 12, 13 and 61 of the KRAS gene in DNA derived from formalin-fixed paraffin-embedded human colorectal cancer (CRC) tumor tissue. The test is intended to be used as an aid in the identification of CRC patients for whom treatment with Erbitux® (cetuximab) or with Vectibix® (panitumumab) may be indicated based on a no mutation detected result. Specimens are processed using the cobas® DNA Sample Preparation Kit for manual sample preparation and the cobas z 480 analyzer for automated amplification and detection.
