October 2021—Clonal hematopoiesis is a significant biological phenomenon and denotes presence of mutations in bone marrow stem cells in the absence of a hematologic malignancy.

June 2019—A high-throughput sequencing panel was found to be more than 90 percent sensitive in detecting urinary tumor DNA in early-stage bladder cancer and in post-treatment surveillance. The approach, reported in April in Cancer Discovery, overcomes some of the challenges urinary cell-free DNA analysis poses, said one of its developers, and is far more sensitive than cytology and cystoscopy.

March 2017—Something about having the letters “DNA” in a test’s name may make the test seem like the last word, the key to a black-and-white, definitive diagnosis. That connotation has been problematic for cell-free DNA sequencing used for noninvasive prenatal testing, because the test is not intended or designed for diagnosis, but only for screening. It’s for that reason, in fact, that some maternal-fetal medicine specialists and clinical geneticists prefer to use the term “noninvasive prenatal screening,” with the acronym NIPS.
