The Manning criteria are a diagnostic algorithm used in the diagnosis of irritable bowel syndrome (IBS). The criteria consist of a list of questions the physician can ask the patient. The answers are used in a process to produce a diagnostic decision regarding whether the patient can be considered to have IBS.
The Manning criteria have been compared with other diagnostic algorithms for IBS, such as the Rome I criteria, the Rome II process, and the Kruis criteria. A 2013 valiadation study found the Manning criteria to have less sensitivity but more specificity than the Rome criteria.
The Manning criteria are: At least 2 of the following:
- Onset of pain linked to more frequent bowel movements
- Looser stools associated with onset of pain
- Pain relieved by passage of stool
- Noticeable abdominal bloating
- Sensation of incomplete evacuation more than 25% of the time
- Diarrhea with mucus more than 25% of the time
