Congenital hypothyroidism (CH) is an endocrine disorder of newborns characterized by the decreased levels of thyroid hormones: thyroxine (T4) and triiodothyronine (T3) in periferal blood. In early perinatal period manifestations of CH are often non-specific, subtle or even non-existent [1-2]. However, the disease, if undiagnosed and untreated, leads to severe mental retardation, as well as to growth and developmental disturbances.
Neoscreen hTSH EIA (enzyme immunoassay) kit is for the quantitative determination of human thyrotropin (hTSH) in blood specimens dried on filter paper as a primary test for screening of babies for congenital hypothyroidism (CH).
