Northstar Select®

Unmatched sensitivity for more treatment opportunities.

50%

Reduction in false negative results1

109%

More actionable CNVs detected

Northstar Select® is a highly sensitive ctDNA liquid biopsy that uses QCT™ technology to guide therapy selection by detecting actionable alterations, even in low tumor fraction samples.

A purpose-built liquid biopsy.

Northstar Select® uncovers treatment opportunities others miss — focused on the genes that matter most for therapy selection.

84 genes
Comprehensive panel targeting clinically actionable biomarkers
High-sensitivity detection of single- nucleotide variants and indels
Covers amplifications (19 genes) and deletions (5 genes)
Fusion detection
MSI
Microsatellite instability analysis
Why sensitivity matters

Low VAF alterations can be found even in traditionally high-shedding tumors1.

The most sensitive liquid CGP

Northstar Select achieves a 2 to 5x lower limit of detection than other liquid biopsies2.

Proven in a head-to-head study

Northstar Select uncovered 50%+ more clinically actionable alterations1.

  • Bower, X., et al., JCO 42, 3072-3072(2024).

  • LOD 95% (limit of detection 95%) is defined as the lowest concentration of an analyte in a sample that can be consistently detected with ≥95% probability. Comparator assays have a LOD 95% that ranges from 0.20% -0.40%.
