The Idylla CDx MSI Test is an in vitro diagnostic test intended for the qualitative
detection of a panel of seven monomorphic biomarkers (ACVR2A, BTBD7, DIDO1,
MRE11, RYR3, SEC31A and SULF2) for identification of microsatellite instability
(MSI) in colorectal cancer (CRC) tissue. The Idylla CDx MSI Test uses formalin-fixed,
paraffin embedded (FFPE) tissue sections from patients with CRC, from which nucleic
acids are extracted, then analyzed using PCR amplification and subsequent melt-curve
analysis. The Idylla CDx MSI Test reports MSI status as either Microsatellite Stable
(MSS) or Microsatellite Instability-High (MSI-H) or invalid.
