About Northstar

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.
