Guardant tests.
CGP, comprehensive genomic profiling; ctDNA, circulating tumor DNA; DNA, deoxyribonucleic acid; EGFR, epidermal growth factor receptor; ER+, estrogen receptor–positive; ESR1, estrogen receptor 1; mBC, metastatic breast cancer; mCRC, metastatic colorectal cancer; OS, overall survival; RNA, ribonucleic acid
*Liquid and tissue testing may be initiated at the same time, but sample processing does not occur concurrently.
†Patients who have a negative Guardant360® Liquid CDx test result for an indicated companion diagnostic marker should be reflexed to tissue biopsy testing using an FDA-approved tumor tissue test, if feasible.
