The xTAG® Cystic Fibrosis (CFTR) v2 assays from Luminex are uniquely designed to be simple yet powerful, and offer the utmost flexibility with the ability to test for the 23 CFTR mutations recommended by the American College of Medical Genetics/American College of Obstetricians and Gynecologists (ACMG/ACOG) and an expanded panel of CF mutations providing broad ethnic coverage across populations. The test provides information intended to be used for carrier testing in adults of reproductive age, as an aid in newborn screening, and in confirmatory diagnostic testing in newborns and children.
Over 2000 mutations have been found in the CFTR gene which is located on the long arm of chromosome 7. Many of these mutations are rare. Most of the mutations are either point mutations or small deletions of between one and 84 base pairs. The most common mutation is a three base pair deletion that results in the loss of a phenylalanine at amino acid 508 (ΔF508). This mutation accounts for 30 to 88 percent of all CF mutations, depending on the ethnic group.1 Frequencies of other mutations also vary by ethnicity.
xTAG Cystic Fibrosis IVD assays are designed to detect and identify the most common CFTR mutations and variants. They offer the ability to test for the 23 CFTR mutations recommended by the American College of Medical Genetics/American College of Obstetricians and Gynecologists (ACMG/ACOG), as well as the flexibility to use an expanded panel of CF mutations to obtain broad ethnic coverage across populations.
The following products are available for targeted CF panel testing:
Obtain the flexibility to meet your mutation coverage needs
Simplify workflow with faster assay turn around times
Utilize IVD cleared assay with 100% overall accuracy and >91% precision (after allowable re-runs)
Many commercial DNA extraction kits are compatible with the xTAG Cystic Fibrosis Kits.
The nucleic acid is amplified using one polymerase chain reaction (PCR).
The amplified DNA is mixed with short sequences (TAG primers) of DNA specific to each target. If the target is present, the primer will bind and will be lengthened through a process called allele specific primer extension. During this extension, a reporter label is incorporated.
Color-coded beads are added to identify the tagged primers. Attached to each differently colored bead is an anti-TAG sequence specific to one of the extended TAG primers. Each anti-TAG only binds to the complementary TAG sequence on the primer.
Samples are read on a Luminex xMAP® instrument that identifies the color of the bead and the presence or absence of labeled target. For each sample, these signals are interpreted by the xTAG Data Analysis Software to determine whether the wild-type and/or mutant alleles for each of the variations have been detected.

Intended Use (EU-IVD/SFDA Approved):
The xTAG® Cystic Fibrosis 71 Kit v2 is a device used to simultaneously detect and identify a panel of mutations and variants in the Cystic Fibrosis transmembrane conductance regulator (CFTR) gene in human blood specimens and blood spots. The panel includes mutations and variants currently recommended by the American College of Medical Genetics and American College of Obstetricians and Gynecologists (ACMG/ACOG) (Table 1), plus some of the world’s most common and North American prevalent mutations (Table 2). The xTAG Cystic Fibrosis 71 Kit v2 is a qualitative genotyping test which provides information intended to be used for carrier testing in adults of reproductive age, as an aid in newborn screening, and in confirmatory diagnostic 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.
