For sample adults aged 40 and older who have ever had a home blood stool test (BSTHEV), BSTHLGYRR2 reports the time since the last home blood stool test in grouped year categories.


This is a time category recode for the time since the most recent blood stool test using a kit at home using the same estimation method used in 2005. All available information was used and the recoded variable was pre-filled with the response to the time category question first, if available. These data are provided by the respondent and are not imputed.

There is a similar version of this variable, BSTOLGYRR1, using the same estimation method as used in 2000.
