• Updated ACS guideline offers Shield as a new choice for over 50 million eligible Americans who are not up to date with their colorectal cancer screening
  • Shield is the first and only FDA-approved blood test included in both ACS and NCCN guidelines

Guardant Health, Inc. (NASDAQ:GH), a leading precision oncology company, announced that its FDA-approved Shield™ blood test is now included in updated American Cancer Society (ACS) Colorectal Cancer (CRC) Screening Guidelines published today. The major screening guideline update recommends Shield as a choice for patients who decline or have not completed stool-based or visual examination screening tests.

In an effort to address persistent screening gaps and rising CRC rates in adults under 65, ACS guidelines now recommend Shield blood-based CRC screening as a new option to expand access and screening participation. Shield is the first and only FDA-approved blood test for primary colorectal cancer screening in average-risk adults age 45 and older and can be completed with just a blood draw during a routine doctor's visit.

CRC is the second leading cancer killer in the United States1 and the number one cancer killer for adults under 50.2 The inclusion of Shield in the updated guidelines acknowledges a central challenge in colorectal cancer screening: more than 50 million eligible adults3 remain unscreened despite established methods like colonoscopy or stool-based testing existing for decades. By recognizing the effectiveness of a blood-based option, the updated guidelines add a new opportunity to reach patients who might otherwise go unscreened.
