Advice

Note that hematocrit parameters differ based on age and sex.

Management
  • Increasing score should prompt consideration of further evaluation or change in therapy.
  • If score is abnormal in subjective components only, it is possible that functional abdominal pain, rather than Crohn’s disease, is responsible.
