Establishing Reference Values for Umbilical Cord TSH in Neonatal Congenital Hypothyroidism Screening

Abstract

Aim: To establish normative umbilical cord thyroid-stimulating hormone (TSH) values in 
neonates at our institution for congenital hypothyroidism (CH) screening. 
Objectives: 
1. To determine the cutoff level of cord TSH in full-term and preterm neonates. 
2. To evaluate the correlation between cord TSH values and birth weight, gender, and 
gestational age.
