If providers can order a complete blood count for their patients, they’re equipped to order
a blood-based CRC screening test.3

Shield detects CRC with high accuracy1,2,5

(CRC Stages I-III)

And advanced adenomas were detected with 20% sensitivity5†

These data add to a growing body of evidence that demonstrates the high sensitivity of our blood-based technology5

1,784 individuals were evaluated in 2021 using our blood-based screening technology in 2 studies, which were presented at ASCO and ACG.5,6,7‡

We are currently conducting a registrational trial, ECLIPSE, to further validate our technology8

The trial aims to enroll ~13,000 patients (ages 45-84) at average risk for CRC.9

How Guardant Health’s blood-based approach identifies CRC1,2§

Our technology achieves high sensitivity by applying a multimodal approach to detect CRC signals in the bloodstream, including DNA that is shed by tumors.1,2,10

*In a study, patients who initially refused colonoscopy preferred screening with a blood-based test over a stool-based test 83% vs 15%, respectively.3

In a study of 309 patients, sensitivity was 94% in Stages I-II, 86% in Stage III (91% overall), 20% in advanced adenomas, and specificity was 92%.5

§The assay is intended to be complementary to and not a replacement for current recommended colorectal cancer screening methods.
Patients with an abnormal blood-based screening result should be referred for colonoscopic evaluation.

Shield™ is a qualitative laboratory developed test intended to detect colorectal neoplasia by identifying genomic and epigenomic alterations in cell-free DNA and proteomic changes in plasma from blood collected in Guardant blood collection tubes.
  • The assay is intended to be complementary to and not a replacement for current recommended colorectal cancer screening methods
  • Patients with an "abnormal signal detected" Shield test result should be referred for colonoscopic evaluation
  • A "normal signal detected" Shield test result does not preclude the presence of colorectal neoplasia, and patients should continue participating in guideline-recommended screening programs
  • Shield was developed, and its performance characteristics determined, by the Guardant Health Clinical Laboratory in Redwood City, CA, USA, which is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) as qualified to perform high complexity clinical testing. This test has not been cleared or approved by the US FDA
