The device description and performance studies focus on traditional molecular biology techniques and do not mention any AI or ML components.
No.
This device is a diagnostic test kit used to detect and identify mutations in the CFTR gene for carrier testing, newborn screening, and confirmatory diagnostic testing. It does not provide any therapeutic intervention.
Yes
The device is explicitly stated to be used for "confirmatory diagnostic testing in newborns and children." It detects and identifies mutations in the CFTR gene, which provides information to confirm a diagnosis.
No
The device description lists multiple physical components (reagents, enzymes, buffers, etc.) which are essential for the device's function (detecting and identifying mutations in blood specimens). This indicates it is a hardware-based device, not software-only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the device is used to "simultaneously detect and identify a panel of mutations and variants in the cystic fibrosis transmembrance regulator (CFTR) gene in human blood specimens." This involves testing a sample taken from the human body (blood) in vitro (outside the body) to provide information about a medical condition (cystic fibrosis).
- Specimen Type: The device uses "human blood specimens," which are biological samples taken from the body for diagnostic purposes.
- Purpose: The information provided by the test is 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." These are all diagnostic or screening purposes related to a medical condition.
- Device Description: The components listed are reagents and materials typically used in molecular diagnostic assays performed in a laboratory setting.
The definition of an In Vitro Diagnostic (IVD) device generally includes reagents, instruments, and systems intended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. This device clearly fits this description.

Accuracy of the xTAG CFTR 60 kit v2 was assessed through evaluation of samples representing all alleles (mutcions and polymorphisms) probed by the assay. The majority of samples consisted of left-over, anonymized, banked whole-blood specimens. These specimens were supplemented with genomic DNAs from EBV-transformed lymphoid cell lines, and several custom-designed plasmids engineered to contain 1-2 CFTR mutations each. Archived clinical genomic DNA samples were obtained from a variety of sources.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
a) Method Comparison Studies / Accuracy:
A total of 488 mutant alleles was tested over a total of 396 clinical samples. Some of the clinical samples were compound Hets or homozygous mutants. The xTAG Cystic Fibrosis 60 kit v2 demonstrated 100% accuracy after allowable re-runs.
a) Precision/Reproducibility:
A multi-centre, multi-operator, multi-lot, blinded study design was used to evaluate total variability of the xTAG Cystic Fibrosis 60 kit v2.
The reproducibility of the analytical (post-extraction) steps of the assay was evaluated at 3 independent sites using in order of preference and availability, purified genomic DNAs extracted from clinical (whole blood) samples, purified genomic DNA extracted from lymphoid cell lines, and/or plasmids. Each set of samples representing all mutations and variants probed by the xTAG Cystic Fibrosis 60 kit v2. There were 2 operators per site, each performing 1 run / day across 3 non-consecutive days (3 runs per operator or 6 runs per site). Within a given run, each assay point was run in duplicate. A total of three (3) assay lots were tested (1 lot / site).
Across sites, operators: The xTAG Cystic Fibrosis 60 kit v2 assay detected all 60 mutations, as well as normal (wild-type) alleles, with a precision of > 99.99% after allowable re-runs across 3 sites, between 6 operators (2 per site) and between reagent lots (a total of 3 lots, 1 lot per site). Two samples (Coriell genomic DNA) made a 'No Call' after an allowable rerun at Site 3 (operator 1) whereas one plasmid sample made 3 miscalls at Site 1 between 2 operators. Repoducibility of detection of a compound heterozygote dF508 / F508C was also characterized in this study. Of the 36 replicates of a sample tested, 30 generated a dF508 HET call and 6 generated a dF508 Mu D call. Both results are accurate when taking into consideration the definition of a Mu D call (i.e. only the mutant allele is detected).
Per sample: The xTAG Cystic Fibrosis 60 kit v2 assay detects mutant / wild-type alleles of the 60 loci assayed with reproducibility (after allowed reruns) of 91.67% for allele dF508mut, and 100.00% for the remaining 58 alleles. For reproducibility testing of the 2307insA allele, a plasmid DNA was used. In 3 out of 36 test points this sample was detected as a HET instead of a Mu D however, in the accuracy study, all clinical samples representing the 2307insA mutation (2 Whole Blood DNA and 1 Blood Spot DNA) were correctly identified by this assay.
c) Detection Limit and range of assay:
Genomic DNA samples representing a subset of mutations in the CFTR 60 kit v2 test were assayed at the following concentrations: 300, 150, 50, 25, 12.5, 1.56, 0.78 and 0.39 ng/μL. Each sample was run in duplicate. Genomic DNA, extracted from whole blood, was used as a wild-type positive control in all runs. At each tested concentration, the data across all samples were pooled. The lowest concentration giving an apparent assay failure rate of ≤5% was considered an estimator of the LoD. The proposed assay lower bound (LB) was set at a concentration (C*) lying at or slightly above the estimated LoD. At concentration C*, 22 replicates of each of the 10 genomic DNAs were run along with 8 negative controls dispersed uniformly throughout the plate to determine the LoD. The Lower Bound and Upper Bound of the assay range was determined to be 2 ng/uL and 300 ng/uL, respectively. The LoD was determined to be 1.56 ng/uL.
d) Analytical Specificity / Interfering Substances:
An Interference study was conducted to examine the effects of potential interferents that might be expected to be found in whole blood samples (1500 µg/mL hemoglobin, 200 µg/mL mixture of triglycerides). Eight whole blood samples were split into 6 parts each, and incubated either in the absence of one of the 3 potential interferents, extracted and assayed with CFTR 60 kit v2. No difference was observed between the final qualitative calls made from the untreated vs treated samples. This study showed that none of the potential interferents commonly found in whole blood produced a significant inhibitory effect on the performance of the CFTR 60 kit v2.

Test Principle:
The xTAG Cystic Fibrosis 60 kit v2 is comprised of a single multiplex PCR reaction which is then used in two separate ASPE reactions (A and B) and subsequently two separate bead hybridization reactions (A and B). DNA samples can be screened for 60 CFTR mutations and 4 variants (benien polymorphisms). The 'A' portion of the xTAG Cystic Fibrosis 60 kit v2 simultaneously screens for the 23 muations and 4 variants currently recommended by ACMG/ACOG. plus 1078delT and 16 of the worlds most common and North American-prevalent mutations. The 'B' portion of the xTAG Cystic Fibrosis 60 kit v2 simultaneously screens for 21 CFTR gene mutations.
To enable efficient incorporation of biotin-dCTP during the Allele Specific Primer Extension the PCR product is treated with Shrimp Alkaline Phosphatase (SAP) to inactivate remaining nucleotides (especially dCTP), and with Exonuclease I (EXO) to degrade any primers left over from the PCR reaction. Following SAP/EXO-treatment, a 5-JL aliquot of the treated PCR product is used in each of the ASPE ' A' and 'B' reactions. Each ASPE reaction product is sorted by hybridization to the universal array (Bead Mix A and B) in the presence of hybridization buffer, and then incubated with Streptavidin, R-Phycoerythrin conjugate (reporter solution). Samples are read on the Luminex® 100/200 andyzer and fluorescence values captured in the Output.csv files are analyzed by the xTAG Data Analysis Software (TDAS CFTR),
For each sample analyzed by the xTAG Cystic Fibrosis 60 kit v2, an output file containing MFI signals from the Luminex instrument is generated. The proprietary software component of this product analyzes this output data file, to provide a final qualitative genotype for the sample. The user must select between 2 options for to running the assay:
Option 1: Full Panel (60 mutations/deletions + 4 variants). Option 2: ACMG/ACOG panel (23 mutations and deletions).
