Question
What are the impacts of neonatal thyroid hormone weak positivity on infants?
Answer
Neonatal thyroid hormone weak positivity may indicate thyroid dysfunction, suggesting a congenital hypothyroidism screening. If thyroid hormone levels remain elevated, further checks of T3 and T4 are necessary. If T4 levels are low and TSH is significantly high, a diagnosis of hypothyroidism can be confirmed, and timely treatment should be initiated.
