AbstractDeficient in the production of thyroid hormone or any defect in thyroid hormone receptor activity can lead on to hypothyroidism. Congenital hypothyroidism (CH) is one of the most common preventable causes of mental retardation in children. In our study all the babies were screened by intravenous blood samples collected between 4896 hours of age and identified 3 babies with CH. Along with CH screening, necessary investigationsdone were blood grouping and serum bilirubin as a standard hospital policy. The TSH was measured by Electrochemiluminescence immuneassay method. Newborn screening for congenital hypothyroidism (CH) by intravenous blood TSH screening in our institute has been effective as a screening tool. From our study, there is no doubt that CH screening fits into the criteria of the diseases that needs to be screened in India, as the incidence in our study of nearly 1:1050 is high and should not be ignored.
