Diagnostic value of fecal calprotectin
Faecal calprotectin was significantly elevated in patients with NEC. Using the faecal calprotectin of the study cohort, at a cut off value of 75 µg/g, faecal calprotectin as a diagnostic tool yielded a sensitivity of 65% and specificity of 63% with AUC of 0.74 (Figure 1). Increasing the cut off to 100 µg/g increased the specificity to 100%, however it resulted in a loss of sensitivity to 40% only.
