Background: Necrotizing enterocolitis (NEC) is one of the most prevalent digestive emergencies in neonates, leading to mortality and morbidity in premature neonates. Since there is no specific test for NEC diagnosis, only clinical symptoms and radiological findings are used for diagnosis. Therefore, if a reliable biomarker found to detect NEC, it can help to reduce the mortality and morbidity; hence, the present study evaluated the stool calprotectin levels in the infected and noninfected neonates weighing <1500 g. Methods: This case-control study was performed on 35 neonates with NEC and 35 healthy neonates. Demographic information and calprotectin levels were measured, and the values were recorded and compared between the two groups. Results: The results of this study revealed that the level of stool calprotectin in the case group with the mean of 459.66 ± 172.63 was significantly higher than the control group with the mean of 103.03 ± 30.97 (P < 0.001). Furthermore, the level of calprotectin had a significant relation with the severity of the disease. Moreover, this biomarker can be a good diagnostic criterion for detecting NEC (cutoff >176 μg/g, sensitivity = 97.14%, Specificity = 100%, P < 0.0001). Conclusion: Given that the level of calprotectin in the stool was not associated with factors such as the sex of neonate, gestational age, birth weight, and type of delivery, it appears that stool calprotectin level can be used as a reliable biomarker for NEC diagnosis.
