Guardant Health partners with Patrick Dempsey for emotional colorectal cancer screening video

Guardant Health, maker of the Shield blood test for colorectal cancer, released a new video featuring actor Patrick Dempsey to raise awareness of the disease.

In the one‑minute clip, Dempsey watches a projection showing that 55,000 Americans die each year, many in their 40s and 50s, and urges viewers over age 45 to discuss screening with their doctors.

The video highlights Guardant’s Shield test, which received FDA approval in 2024 for average‑risk adults 45 and older, and places the brand prominently at the end.

Dempsey, who has worked with Amgen and Pfizer, began collaborating with Guardant in March and previously appeared in a spot where he had his own blood drawn for the test.
