Thyroid-stimulating hormone (TSH) is a glycoprotein hormone with a molecular weight of about 30 000 Da, that consists of two subunits – alpha and beta. TSH is secreted by the frontal lobe of the hypophysis and stimulates the thyroxin and triiodothyronine synthesis in the thyroid gland. A sharp increase of TSH concentration in blood is detected in the newborns just after the birth. If a thyroid gland function of the newborn is normal, TSH 

concentration decreases in several days after birth and then remains stable at the normal level (< 20 μIU/ml of blood). The increased THS concentration in the blood of newborn on 3rd-5th day of life is the earliest diagnostic indicator of the congenital primary hypothyroidism. 

NeonatalEIA-TSH kit is intended for the quantitative determination of thyroid-stimulating hormone in dry spots of blood of newborns.
