Since 2020, Guardant has established public-private partnerships (PPPs) with leading healthcare institutions and cancer centers in Europe including The Royal Marsden NHS Foundation Trust (UK), Vall d'Hebron Institute of Oncology (Spain), and Policlinico Gemelli (Italy) to localize advanced diagnostic testing, generate clinical/economic evidence, and ultimately expand reimbursement and adoption. These partnerships make it possible to deliver high quality, clinical grade testing, similar to tests administered in the U.S., with local validation supporting research, delivering faster diagnoses, and increasing access to targeted treatments.

About Guardant360® Liquid Guardant360 Liquid is a blood-based test that analyzes tumor DNA fragments circulating in the blood (cfDNA) to identify genetic mutations in advanced solid tumors, helping oncologists find targeted therapies. It offers an alternative to tissue biopsies, providing comprehensive genomic profiling (CGP) to guide personalized treatment for a wide range of solid cancers including lung, breast, colorectal, and prostate cancer. Guardant360 Liquid is guideline-complete across all advanced solid tumors, and has been clinically validated in more than 1,500 publications and research abstracts. About Guardant Reveal® Guardant Reveal is a tissue-free liquid biopsy test that detects minimal residual disease (MRD) and monitors recurrence in early-stage colorectal, breast, and lung cancers, helping oncologists guide treatment decisions. In addition to MRD detection, Reveal can be used for late-stage therapy response monitoring for patients with solid tumors. Guardant Reveal therapy response monitoring can be initiated at any time during a patient's treatment journey, offering clinicians flexibility and actionable insights. The first clinical-validation study of pan-cancer chemotherapy monitoring published in The Journal of Liquid Biopsy showed that Guardant Reveal predicts long-term patient benefit up to 18 months earlier than standard clinical measures. About Guardant360® CDx Guardant360 CDx is the first FDA-approved liquid biopsy for comprehensive genomic profiling. It detects multiple genomic alterations across all solid tumors and is approved as a companion diagnostic for therapies in non-small cell lung cancer, breast cancer, and colorectal cancer.
