Congenital hypothyroidism (CH) is a treatable cause of intellectual disability in children, hence the importance of newborn screening for hypothyroidism.
First time newborn screening for a congenital disorder was done by Prof. Dr. Robert Guthrie in 1960, in USA for phenylketonuria. Screening was done first time in 1965. This led to early diagnosis and treatment of hypothyroidism which in turn improved intellectual outcome in babies born with CH. This created a worldwide interest in screening for hypothyroidism. In India screening for CH was done first time at B. J. Wadia Hospital, Mumbai in 1982 using cord blood sample.
