Because stool obviously transmogrifies as it exits the rectum.
Stool contained on the end of one’s finger after performing a rectal exam and then transferred to a hemoccult card causes hemoccult cards to give wrong readings and therefore the results “may not be accurate.”
However, stool that is plopped in the toilet, mixed with water, possibly urine, and whatever else is growing in the toilet bowl … no problemo. Definitely accurate.
This “results may not be accurate” disclaimer is reportedly added to every stool sample the hospital reports because the hemoccult card manufacturer said that the cards are only to be used for “formed stool”. Not sure how the lab tests to determine whether the sample is “formed” or is “diarrhea,” but I’m not a lab technician. Perhaps they test the moisture content of the sample prior to actually applying the requisite number of drops of hemoccult developer.
The hospital also reportedly had an entire committee meeting where multiple educated professionals and administrators thought it was appropriate to include the “results may not be accurate” disclaimer given the manufacturer’s guidelines.
That then begs the question that if the stool results “may not be accurate,” then why is the hospital reporting on the results at all?
I’m sure that a fear of liability for not following the manufacturer guidelines in using the product had nothing to do with the committee decision, either.
