For sample adults aged 40 and older who have ever had a Cologuard test and reported the time since the last Cologuard test in a number and time period format (e.g., 30 days since the most recent test), COLGLTP reports the type of time unit (days, weeks, months, or years). COLGLTP should be used alongside COLGLNO, which reports the number of time units since the last Cologuard test.

Please refer to COLGEV for more information about 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."
