Guardant360 CDx

The comprehensive tumor mutation profiling test for guiding treatment decisions


Guardant360® is a next-generation sequencing (NGS) liquid biopsy test that analyzes circulating tumor DNA (ctDNA) from blood samples. The test provides guideline-recommended genomic results to oncologists in just 7 days from sample receipt at the laboratory, for timely assigning targeted therapy to patients with advanced solid tumors.


Guardant360® detects somatic variants in a targeted panel of 74 genes and high microsatellite instability (MSI-High). The test is approved by FDA as a companion diagnostic for non-small cell lung cancer (NSCLC) treatments – TAGRISSO® (osimertinib), RYBREVANTTM(amivantamabvmjw), and LUMAKRASTM(sotorasib).

Liquid biopsy is a quick and feasible alternative to traditional tissue biopsy


With liquid biopsies, you can avoid the complications and delays of invasive tissue biopsies. The quick turnaround time of liquid biopsy test results which is approximately seven days upon sample receipt in the laboratory makes quick and accurate treatment decisions a reality. Comprehensive liquid biopsies are a feasible alternative to pick up actionable tumor mutations missed during tissue biopsies.

Alterations covered

Guardant360 covers alterations in over 70 genes relevant to multiple solid tumors including MSI-High.

alterations covered
+ Sample requirement

Two 10ml streck tubes.

+ Who and when to get tested

Patients with advanced solid-tumor cancers before first-line therapy or at progression.

+ Storage and shipping conditions

Ship same or next day at room temperature. Do not freeze or refrigerate.

Remark: When no biomarker is identified with Guardant360®, Guardant360 TissueNextTM is an alternative assessment when initially requested by the ordering provider.

Enabled more complete biomarker assessment than standard-of-care tissue testing

alterations covered

Guardant360® CDx liquid biopsy result available for 95% of patients for the 4 biomarkers with FDA-approves therapies vs 31% with tissue.1
