Idylla EGFR primary plus T790M. EGFR mutation status of 1 to 4 slides of a total of 7 T790M positive tested specimens (between 2,3 and 18% VAF), in addition to the primary EGFR mutation, were determined using Idylla™ EGFR cartridges. Total CQ values were mentioned to assess the amplifiability of the DNA. T790M VAF in Idylla™ samples was estimated using the formula (TC% Idylla™/TC% original sample)* T790M% original sample. Green indicates concordant result, red indicates non-concordant result (at least one of the expected mutations not detected). Yellow in the EGFR column indicates that only one of two expected mutations was detected
