A 21-year-old member asked:

Is the stool test "positive" when there is only a small speck of blue-green color on the test area?

Yes, minimally so: Yes, but may be equivocal. Depends on the circumstance, diet, etc. Worth repeating. If patient is at risk for colon polyps or cancer, by age, family history, or symptoms/physical exam, then the stool test is not the make or break issue in deciding to do further evaluation. If there are other GI symptoms, the decision for evaluation depends on histroy and physical.

Is it bad to hold a stool until a convenient time?

2 doctor answers3 doctors weighed in
Dr. James Ferguson
Pediatrics 46 years experience
Hard, bulky stool: Children who avoid a stool for whatever reason can later forget to empty. This may result in a hard or bulky stool that is painful to pass. To avoid pain, younger children may try to avoid having stools & older kids may just want to avoid going at school. Over time, this can weaken the emptying function & cause a recurrent problem with slow transit/poor emptying & require specific program to fix.

Can benefiber chewables cause a different color in stools?

Dr. Crystal Twynham
General Surgery 33 years experience
Sometimes: Benefiber can sometimes trap bile acids. A variation in the amount of bile acids in your stool can cause a change in the color. It is not dangerous, and the benefits of fiber far outweigh any psychological concerns about what color your stools are! ** good luck!
