Bowel transit time
Normal values:
The bowel transit time varies even in the same person. The first of the color should appear in the stool about 12 to 14 hours after it is taken. The last of the color will appear within 36 to 48 hours.
What abnormal results mean:
If the times are much longer, 72 hours or more, it may indicate a slowed bowel function. A high fiber diet should speed the bowel transit time up.
