Cell-free DNA (cfDNA) is an emerging biomarker that already has significant clinical utility. With further development, cfDNA characterization may become a ubiquitous companion modality for diagnosis, prognosis, treatment selection, and recurrence detection for myriad medical conditions. In this chapter, ...
Dedicated to oncology, women’s health, and organ health. Natera’s cell-free DNA tests help protect health and inform more personalized decisions about care.
Objective: First, to assess what was the uptake of cell free DNA (cfDNA) testing after a combined test and the maternal and fetal factors that influenced this decision, and second, to assess the uptake and factors that influence the choice of invasive testing....
Bronchial washing fluid, obtained by lavage with saline after tumor biopsy or brushing, and the supernatant of bronchial washing fluid are thought to contain cell-free DNA that would be potentially applicable for EGFR testing.METHODS: From among patients with suspected adenocarcinoma or non-small ...
Obstet Gynecol Surv 2016;71(3):146-147 One of the most important technical advances in prenatal care in recent times is analysis of cell-free DNA (cfDNA) in the maternal plasma to screen for fetal aneuploidy. Use of cfDNA screening for aneuploidy was clinically introduced in 2011 in the Uni...
Cell-free DNA noninvasive prenatal screening for trisomies 21, 18, and 13 has been rapidly adopted into clinical practice. However, previous studies are limited by a lack of follow-up genetic testing to confirm the outcomes and accurately assess test performance, particularly in women at a low ...
TheAmerican College of Obstetricians and Gynecologistsrecommends that only high-risk mamas-to-be should get cell-free fetal DNA testing. The reason? The test has not been sufficiently evaluated in low-risk groups (or on those carrying more than one baby). You're considered high-risk if you'...
Plasma cell-free DNA (cfDNA) testing plays an increasingly important role in precision medicine for cancer. However, circulating cell-free tumor DNA (ctDNA) is highly diluted by cfDNA from non-cancer cells, complicating ctDNA detection and analysis. To identify low-frequency variants, we developed...
Known to be present in the blood of cancer patients for decades, cell-free DNA (cfDNA) is beginning to inform on tumor genetics, tumor burden, and mechanisms of progression and drug resistance. This substrate is amenable for inexpensive noninvasive testing and thus presents a viable approach to...
Cell-free DNA (cfDNA) has become a comprehensive biomarker in the fields of non-invasive cancer detection and monitoring, organ transplantation, prenatal genetic testing and pathogen detection. While cfDNA samples can be obtained using a broad variety of approaches, there is an urgent need to stand...
