Abstract

Abstract

Objective To explore the positive cut-off value in neonatal screening for congenital hypothyroidism (CH) in the center of Neonatal Screening, so as to improve screening efficiency and reduce false positive rate. Methods Heel blood samples were taken from the newborns born after72 hours, dropped in special S&S903 filter paper and delivered to the neonatal screening center within the prescribed period of time.DELFIA was applied to detect the concentration of thyroid-stimulating hormone (TSH) .Result Totally 529918 blood sample were screened from the 2012 to the 2016.Among them 529645 newborns were normal, 203 neonates were diagnosed with CH, 70 with high TSH hyperlipidemia, the total detection rate was 1:1941, and the incidence of CH was 1:2 610. According to the results, the cut-off value of the screening of CH in the center of Neonatal Screening was 9.0 m IU/L, the sensitivity was 100%and specifility was 98.38%, misdiagnosis rate was 0%.Conclusion The cut-off value of CH was 9.0 m IU/L in the center of Neonatal Screening, which is suitable for the people in 6 Prefecture/City of Yunnan Province, and also provides the basis for neonatal scree of CH in the future.
