There are three billion letters, three billion nucleotides that make up our genome. Our proprietary technology has the ability to detect and quantify disease at single base-pair resolution. Our name speaks to this unique technology, and we are focused on applying it to various disease states to help more patients.Mission, Vision, Values
At the Forefront of
Our proprietary Quantitative Counting Templates, or QCTs™, power our ability to detect and measure tiny and sparse disease-related DNA fragments, or molecules, at the single base-pair level. Several common and severe recessive conditions screened for prenatally can be caused by single-base pair alterations.
Our QCT technology enables quantifying these tiny variations using cell-free DNA. We believe this quantification will open the door to exponential improvements in prenatal screening, liquid biopsy, and beyond.
Moving Prenatal Screening and Liquid Biopsy Forward
We assess fetal risk for recessive conditions and aneuploidies from maternal blood.
UNITY Screen™ includes a carrier screen as well as a single-gene (for recessive conditions) and aneuploidy NIPT and only requires a maternal blood draw at 10+ weeks to assess fetal risk. No paternal sample needed.
Northstar Select™ and Northstar Response™ are now available for commercial use.
Northstar Select™ helps determine the most appropriate first line therapy, and Northstar Response™ helps monitor if the therapy is working.
