Question
How to diagnose if a newborn has congenital hypothyroidism?
Answer
Based on the newborn’s condition and detection indicators, if the T4 value is within the normal range (77-205) and the TSH value is elevated (0.5-4.8), these data alone are not sufficient for a definitive diagnosis of hypothyroidism. It is recommended that parents observe if the child has been born prematurely, has a low birth weight, an extended jaundice period, abdominal pain after birth, constipation, and pay attention to symptoms such as being often in deep sleep, slow response, and low crying voice. Regular checks of thyroid function should be conducted to ensure timely discovery of any issues.
