Hi, We have a case of a very high Calprotectin 3723 ug/g (reference values <50 ug/g). The patient is known of having Crohn disease since 14 yrs. Is it common to have a very high Calprotectin in these patients. Thanks Ihssan Dr. Ihssan Bouhtiauy, PhD, FCACB, FACB, MBA Chef clinique du département de Biochimie Réseau de santé Vitalité 275 Blv.
