cell-free DNA

SensID specializes in the development, manufacture, and marketing or reference materials and quality controls for DNA-based diagnostics.

The company's first quarter revenues were driven by sales of its noninvasive prenatal screening and carrier screening tests.

Take2 was founded by Chinese University of Hong Kong researchers and will commercialize a cell-free DNA test for early cancer detection.

The company filed its first suit against Natera in March, claiming the firm's kidney transplant test infringes patents underlying CareDx's AlloSure test.

The Medicare contractor said in its draft guidance it would provide limited coverage for the cell-free DNA assay, which should be used as a supplemental test.

The company will use the money to launch its first product, Unity, a noninvasive prenatal test for recessively inherited single-gene disorders.

CareDx claims that Natera is infringing on two of its patents related to non-invasive monitoring of organ transplant rejection through cell-free DNA analysis.

The study adds to growing evidence around the utility of cell-free DNA testing in lung cancer patients, while highlighting shortcomings of the approach.
