Technical validation of an RT-qPCR in vitro diagnostic test system for the determination of breast cancer molecular subtypes by quantification of ERBB2, ESR1, PGR and MKI67 mRNA levels from formalin-fixed paraffin-embedded breast tumor specimens

Table 6 Concordance of dichotomized test results between sites by qPCR system and between different qPCR platforms. The calculation of concordance between the two platforms is based on data from study 2
