Regular use of anti-inflammatory agents (NSAIDS) may cause enteropathy in some individuals influencing FC concentration; therefore, it is recommended to stop NSAIDS several weeks before FC stool measurement. Calprotectin is measured by ELISA assays and a number of commercial kits are available on the market. During the Study period approximately 200 to 250 cases satisfying the Inclusion and Exclusion criteria were expected in each group. So after selecting the first eligible case in each Group by simple random procedure, every 10th eligible case in that Group have been enrolled till the required sample size of 22 cases in each Group was achieved. There was statistically significant difference in fecal calprotectin concentration between CTP class A and C, between class B and C. Though mean fecal calprotectin concentration was high in CTP class B as compared to class A, the difference was not statistically significant.
