For sample adults aged 40 and older who had ever had a Cologuard test, COLGLDMO reports the month of the most recent Cologuard test. COLGLDMO should be used with COLGLDYR, the year of the most recent Cologuard test.

Refer to COLGEV for more information on Cologuard testing variables.


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."
