This article summarizes the clinical features of 36 cases of congenital hypothyroidism (hypothyroidism) diagnosed during neonatal screening. The results showed that caesarean section was more common in full-term infants with birth weight> 300 g at birth. There were 29 cases (81%) with clinical manifestations at diagnosis, delayed jaundice and most common constipation. According to clinical manifestations diagnosed as congenital hypothyroidism only 2 cases (6%). Neonatologists should be aware of congenital hypothyroidism should be aware of clinical manifestations. Thirty-six cases (100%) of the first screening paper blood TSH values were higher than normal, suggesting that elevated blood TSH value is the most sensitive congenital hypothyroidism diagnostic indicators
