Capillary blood samples from three hundred healthy, full-term newborn within 48 and 120 hours of delivery, were collected on filter paper for analysis of thyroid-stimulating hormone (TSH). Blood was collected by pricking the heel of the newborn and spotted and dried on filter paper cards. The samples were analysed by immunoradiometric assay (IRMA) to determine the TSH level. Some fifteen percent of a total 1928 deliveries at two hospitals during a period of one year were included in the study. Male:female ratio was 1.1:1. There was no maternal history of thyroid disease. None of the babies had any clinical feature of hypothyroidism. On analysis, TSH level ranged from 0.6-19.3 microU/ml with a mean (SD) of 7.19 (4.21) microU/ml. TSH assay from dried filter paper blood spot is technically possible and is a cost-effective and reliable method for a screening programme. This is the first time in Bangladesh that this method has been successfully carried out.

D003362	Cost-Benefit Analysis	A method of comparing the cost of a program with its expected benefits in dollars (or other currency). The benefit-to-cost ratio is a measure of total return expected per unit of money spent. This analysis generally excludes consideration of factors that are not measured ultimately in economic terms. In contrast a cost effectiveness in general compares cost with qualitative outcomes.

D003409	Congenital Hypothyroidism	A condition in infancy or early childhood due to an in-utero deficiency of THYROID HORMONES that can be caused by genetic or environmental factors, such as thyroid dysgenesis or HYPOTHYROIDISM in infants of mothers treated with THIOURACIL during pregnancy. Endemic cretinism is the result of iodine deficiency. Clinical symptoms include severe MENTAL RETARDATION, impaired skeletal development, short stature, and MYXEDEMA.

D001459	Bangladesh	A country in Southern Asia, bordering the Bay of Bengal, between Burma and India. The capital is Dhaka.
D013972	Thyrotropin	A glycoprotein hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Thyrotropin stimulates THYROID GLAND by increasing the iodide transport, synthesis and release of thyroid hormones (THYROXINE and TRIIODOTHYRONINE). Thyrotropin consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the pituitary glycoprotein hormones (TSH; LUTEINIZING HORMONE and FSH), but the beta subunit is unique and confers its biological specificity.
