March 4, 2026 — Leads & Copy — Guardant Health, Inc. (Nasdaq: GH) has launched Shield Across America, a mobile screening tour to provide access to Shield, its FDA-approved blood test for colorectal cancer (CRC) screening.
The tour will visit over 100 communities across the U.S., from Las Vegas to Hartford and Atlanta, aiming to educate patients and offer screening opportunities via a mobile lab. The initiative coincides with National CRC Awareness Month.
The Shield Across America tour will focus on rural areas facing barriers to colorectal cancer screening and high incidence and mortality rates.
CRC is the second leading cause of cancer-related deaths in the U.S., and the leading cause for those under 50. More than 54 million eligible Americans do not complete CRC screening due to inconvenient options. Shield Across America seeks to eliminate these barriers by expanding access to Shield through mobile screening lab stops.
Guardant Health co-CEO AmirAli Talasaz said the Shield Across America tour addresses the challenge of access to colorectal cancer screening. By bringing screening to where people live, work, and enjoy, with a focus on rural communities, the company aims to encourage more people to get screened and close the nation’s screening gap.
According to the company, 93% of patients completed Shield tests in the first 100,000 tests ordered. The National Comprehensive Cancer Network included the Shield blood test in its updated CRC screening guidelines.
Built on Guardant’s technology, Shield is covered by Medicare, the Veterans Affairs Community Care Network, and TRICARE for active-duty service members. It is commercially available across the U.S.
Shield is a methylation partitioning cell-free DNA (mp-cfDNA) blood-based screening test that detects alterations associated with colorectal cancer. It is for individuals at average risk, age 45 or older, and is not for individuals at high risk for colorectal cancer. A positive Shield result requires a colonoscopy evaluation.
