Abstract A pilot study was performed to determine the incidence of congenital hypothyroidism (CH) in Turkey and to build a model for nationwide screening. From December 1991 to December 1992, 30097 newborns were screened for CH using a primary measurement of thyroid stimulating hormone in capillary blood on days 3–5 of life. Samples were obtained in collaboration with the ongoing nationwide phenylketonuria screening programme. Eleven cases of primary CH were detected giving the incidence of 1:2736. Recall rate was 2.3%. Replacement therapy with l-thyroxine was started after the confirmation of diagnosis. The median age at the initiation of replacement therapy was 23 days (range 7–35 days). Conclusion The incidence of CH is notably higher in Turkey than reported in most other countries. Iodine deficiency and/or dyshormonogenesis might contribute to this high incidence. This result emphasizes the necessity of a nationwide screening programme.
