title: Screening for congenital hypothyroidism: a three year experience.
abstract: Experience with a nationwide screening programme for congenital hypothyroidism in New Zealand is reported. Using radio-immune assays for thyroxine (T4) on all newborns, and thyroid stimulating hormone (TSH) determinations on samples with T4 levels below the 5th percentile, 160 899 babies were screened and 33 cases of primary hypothyroidism were detected (incidence 1: 4875). Screening resulted in treatment beginning within the first three weeks of life.
