【Abstract】 Because of the irreversible mental retardation of congenital hypothyroidism can be prevented by early treatment, the importance of early diagnosis of this disease has been emphasized.We choose the method of measuring serum TSH for screening neonatal hypothyroidism by cord blood. As an initial screening test, it has a higher specificity for the diagnosis of primary hypothyroidism and the blood sample is easy to obtain. Excess serum is also readily available for repeated analyses.Cord serum TSH was determined in 8018 infants. The distribution of the values is skew. The median value was 7.7 μIU/ml. The incidence of neonatal hypothyroidism was 1/8018 in our investigation.更多还原
