Redefining the standard for ultra-sensitive and early MRD detection
Pathlight™ is a blood-based, multi-cancer MRD test that enables clinicians to monitor cancer progression from early detection through relapse and metastasis—supporting confident, informed treatment decisions at every stage of care.

Breaking barriers in clinical performance
With its first indication in breast cancer, Pathlight has been shown to deliver a 96% detection rate at baseline (pre-treatment) across stages and subtypes, 94% in estrogen receptor-positive (ER+) breast cancer – a patient population in which first-generation MRD tests can struggle to exceed 80%.
In a published study1, Pathlight delivered 100% sensitivity, 100% specificity and a 13.7-month lead time, a powerful advantage for detecting recurrence early.
Pathlight also breaks the 1ppm sensitivity barrier – enabling the detection of early, small tumors while they’re still treatable.

A personalized test powered by unparalleled knowledge of each tumor's source code
First-generation MRD tests often rely on detecting single nucleotide variants (SNVs), which are susceptible to technical noise, leading to false positives that impact specificity and false negatives that decrease sensitivity, potentially leading to shorter lead times across many tumor types.
Pathlight works differently by focusing on large-scale genomic alterations called structural variants (SVs) that are patient- and tumor-specific. SVs are much less susceptible to detection noise. This results in a test with 20x greater analytical sensitivity1 than first-generation MRD assays, and 100% analytical and clinical specificity.
Fast answers.
Meaningful impact.
Personalized tumor fingerprint development and initial blood test: results are expected to be available 2 – 3 weeks from receipt of both tissue and blood at the laboratory.
Subsequent blood tests: results are expected to be available 1 – 3 days from receipt of blood at the laboratory.
Robust performance across multiple solid tumor types.
