The physician and or parent will be asked for a brief progress report every 6-12 months. Consultation with a qualified specialist is advised when diagnostic testing is undertaken. If repeated screens show low T4, serum will be requested. If T4 is low and TSH is high, treatment can be started as soon as serum is obtained. Premature infants may have a physiological reduction in blood T4 levels.
Premature infants have about the same incidence of hypothyroidism as full term infants.
Premature infants with abnormal thyroid tests need follow-up testing to ensure that the low T4 levels rise to the normal range as the infant matures. Repeat screens may be submitted. Treatment of congenital hypothyroidism is simple and effective. Pediatric endocrinology consultation should be obtained to determine recommendations for medication adjustment and follow-up for the child. The Newborn Screening Case Management staff can recommend a consultant in your area.
