All newborns in Singapore are tested for Congenital Hypothyroidism by their umbilical cord blood Thyroid-Stimulating Hormone (TSH) level. If cord blood TSH level is high, they undergo a repeat confirmatory blood test of TSH and thyroid hormone levels. If the blood test shows a high TSH level, which confirms the diagnosis of Congenital Hypothyroidism, they will require special investigations including a scintigraphy scan to determine the cause.
Treatment for Congenital Hypothyroidism is administered with an oral replacement of thyroxine tablets once a day. The dose of thyroxine will be adjusted as the child grows and based on the blood test results.
Parents should contact a paediatrician specialising in endocrinology for the management and follow-up of a child with Congenital Hypothyroidism.
