For sample adults aged 40 and older, COLGEV reports if the person had ever had a Cologuard test. COLGEV was introduced in 2018 as part of a series of questions covering Cologuard testing.

The 2018 Field Representative's Manual noted: "Cologuard is a new type of stool test to check for colon cancer. Unlike other stool tests, Cologuard looks for changes in DNA in addition to checking for blood in your stool. The Cologuard test is shipped to your home in a box that includes a container for your stool sample."
