How this service works
Manning 1978 IBS symptoms. Six caller-assigned flags, 1 each, max 6: visible abdominal distension, pain relief with bowel movement, more frequent stools at pain onset, looser stools at pain onset, rectal mucus, incomplete evacuation. Score is the count of true flags (0-6). More symptoms made IBS more likely; no published cutoff. Count only. Not a diagnosis, not Rome III/IV. magent does not examine the patient.
Output
Returns a Manning IBS score as an integer from 0 to 6, representing the count of symptom flags that were marked true. Higher scores indicate more symptoms associated with IBS per the Manning 1978 criteria. No diagnosis is made and no cutoff is applied.
Example use cases
Primary care IBS symptom triage
“My patient has visible abdominal distension, pain that eases after a bowel movement, and looser stools when pain starts — but no rectal mucus, no feeling of incomplete evacuation, and no increase in stool frequency with pain. What's their Manning IBS score?”
Gastroenterology clinic pre-assessment
“Before the patient's GI appointment, I need to score them on the Manning 1978 criteria. They report rectal mucus, incomplete evacuation, and pain relief after bowel movements, but deny abdominal distension, more frequent stools with pain, or looser stools with pain. Can you give me the Manning score?”
Research data pipeline IBS screening
“I'm processing intake survey responses and need Manning scores. This respondent answered yes to all six Manning criteria: abdominal distension, pain relief with bowel movement, more frequent stools at pain onset, looser stools at pain onset, rectal mucus, and incomplete evacuation. What's the score?”

Endpoint
GEThttps://api.magentlab.com/api/calc/manningWhen to prefer
Use this endpoint when you need a quick, structured Manning 1978 IBS symptom count for clinical documentation, decision support, or research pipelines. Prefer it over Rome III/IV-based tools when the specific Manning 1978 six-symptom framework is required, such as for legacy research comparisons or when a simple additive score (not a diagnostic algorithm) is needed.
Side effects
- Missing any of the six required boolean query parameters returns a validation error
- Non-boolean values for any flag cause a schema validation failure
- Payment not included or insufficient balance results in a 402 Payment Required response
