title: Towards evidence-based emergency medicine: best BETs from the Manchester Royal Infirmary. BET 3: Super calprotectin will not expedite your discharge.
abstract: A short-cut review was carried out to establish whether measurement of the plasma calprotectin (S100A8/A9) level can be used to enable safe exclusion of acute appendicitis in children presenting to the emergency department with abdominal pain. Four studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are shown in table 3. The clinical bottom line is that there is currently no evidence to suggest that serum calprotectin is superior to standard inflammatory markers for the exclusion or confirmation of suspected appendicitis. Clinical examination findings remain the cornerstone of surgical decision-making.
