Biomarkers for assessing disease activity in inflammatory bowel disease

The primary objective is to determine the diagnostic accuracy of three commonly studied biomarkers (serum CRP, FC and SL) for assessing disease activity in patients with established IBD (i.e. UC or CD) presenting with symptoms suggestive of active disease.

A secondary objective is to investigate sources of heterogeneity by disease type (i.e. UC or CD), disease severity (e.g. mild, moderate or severe disease), disease location (e.g. distal or proximal involvement) and age.

This is a protocol.
