Comments Testing is performed using the Luminex xTAG Cystic Fibrosis 60 v2 (CF 60 panel) to simultaneously detect and identify a panel of 60 mutations and variants in the Cystic Fibrosis transmembrane conductance regulator (CFTR) gene in human blood specimens. The panel consists of mutations and variations currently recommended by the American College of Medical Genetics and American College of Obstetricians and Gynecologists (ACMG/ACOG), plus some of the world's most common and North American-prevalent mutations. The CF 60 panel is a qualitative genotyping test that provides information intended to be used for carrier testing in adults of reproductive age, as an aid in newborn screening, and in confirmatory testing in newborns and children. The kit is not indicated for use in fetal diagnostic or pre-implantation testing. This kit is also not indicated for stand-alone diagnostic purposes.
