In a clinical setting, Guardant products powered by the Infinity platform can have:

Even faster turnaround times

post-sample receipt1

Enhanced sensitivity

with 100x to 1000x more signals available to analyze1

New insights

across the continuum of care, from minimal residual disease to progression1


Precision oncology has advanced our ability to match the right patient to the right treatment at the right time—and we are just getting started.

A new dimension of insights: An epigenomics example1,4

Gene of interest

Genomic profiling offers details into alterations of the genomic DNA…

Methyl groups

...while epigenomic profiling can help detect alterations to the expression of the genome.4,5

Epigenome dynamic landscape

The epigenome is a dynamic landscape providing breakthrough insights to offer a more complete view of cancer.4,6,7


A growing body of evidence demonstrates that epigenetic changes have a tremendous impact on cancer development and progression.4,6

Epigenomic insights, specifically methylation sequencing, can advance multiple precision oncology applications.1

  • AI-backed digital pathology algorithm that is now validated for multiple cancer types.2‡

  • Accurate scoring helps to predict response to immunotherapy.10

  • Orderable through Guardant360 TissueNext with PD-L1—results in 2 to 3 weeks.2


A more precise PD-L1 test for non-small cell lung cancer (NSCLC).2,11

improved PD-L1 detection

AI-powered PD-L1 scoring that accurately classified 22.2% of patients, initially identified as Tumor Proportion Score (TPS) <1%.2,11§

Response rate

up to 62%

In KEYNOTE-189, overall response rates ranged from 33.1% to 62.1%,
depending on TPS.2,10

*Guardant Infinity is not available for patients with advanced-stage cancer tested with any Guardant liquid biopsies. 

Compared with genomic-only detection.1  

Guardant360 TissueNext PD-L1 test powered by Guardant Galaxy is available for NSCLC, breast, urothelial, hepatobiliary, gastric, colorectal, pancreatic, and prostate cancers. Some cases may require conventional determination of PD-L1 status without AI.2  

§Compared to manual pathologist interpretation in the most challenging cases in NSCLC.11 

AI, artificial intelligence; MRD, minimal residual disease; PD-L1, programmed death-ligand 1.
