Product Code NXO Calprotectin, Fecal
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.5180
Definition The Device Is Used For The Measurement, In Human Stool, Of Fecal Calprotectin, A Neutrophilic Protein That Is A Marker Of Mucosal Inflammation. The Device Can Be Used As An Aid In The Diagnosis Of Inflammatory Bowel Disease (ibd), Crohn's Disease And Ulcerative Colitis And To Differentiate Ibd From Irritable Bowel Syndrome.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. Clinical trial data may be submitted as supporting evidence to strengthen the substantial equivalence argument. Most Immunology devices follow this clearance model.
