Why has there been an evolution of testing platforms for CDx (Companion Diagnostic) testing, shifting from in situ hybridization (ISH) and immunohistochemistry (IHC) to PCR and NGS?
A) ISH and IHC are more cost-effective than PCR and NGS.
B) PCR and NGS provide faster results compared to ISH and IHC.
C) ISH and IHC have limitations in sensitivity and specificity.
D) PCR and NGS are less accurate in detecting genetic mutations.
