Codes and Frequencies
For sample adults aged 40 and older who had ever had a Cologuard test (COLGEV, BSTHEV), COLGBST indicates whether the home blood stool or FIT test was conducted as part of a Cologuard test. Prior to 2019, the universe for COLGBST was further restricted to those who had ever had a home blood stool test (BSTHEV).
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."
The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
