targeted cell-free DNA testObjectives: To evaluate the failure rate and performance of cell-free DNA (cfDNA) testing as a first-line screening method for major trisomies, performed by two laboratories using different analytical methods: a targeted chromosome-selective method (Harmony prenatal Test) ...
Summarize and interpret results from exercises distributed to laboratories offering cell-free (cf) DNA screening for Down syndrome.The College of American Pathologists distributed three patient-derived plasma specimens twice in 2018. Sequencing platforms, test methods, results, and responses to supplemental...
Counting-based cell-free DNA screening test fails to identify triploidy-A case report69,XXXnoninvasive prenatal testingultrasoundKey Clinical Message Although noninvasive prenatal testing (NIPT) is a good test with high sensitivity and specificity for trisomy 21, 18, and 13, it remains a screening...
Christian Iseli, PhD2, Liam Brennan3, Magne Osteras, PhD4, Ioannis Xenarios, PhD2, Laurent Farinelli, PhD4 and Bernard Conrad, MD3 Purpose: Cell-free DNA (cfDNA) testing for fetal aneuploidies was broadly implemented for common trisomies and sex-chromosome anomalies (SC...
it would be useful if cell-free fetal DNA could be used for developing a test with a much higher positive predictive value. Because maternal plasma contains a mixture of nucleic acids originating from the mother and the fetus, our research group had initially attempted to develop approaches for...

The MagMAX™ Cell-Free DNA Isolation Kit is designed for enrichment of circulating cell-free DNA (cfDNA) and optimized for use with biological samples such as serum and plasma. The kit is based on MagMAX™ magnetic-bead technology, enabling reproducible recovery of high-quality DNA that is ...
Cell-free DNA (cfDNA) analysis represents a promising method for the diagnosis, treatment selection and clinical follow-up of cancer patients. Although its general methodological feasibility and usefulness has been demonstrated, several issues related to
