Question
The newborn’s disease screening shows the thyroid hormone level to be as high as 13.4, with the normal range being 6-9. The T3T4 levels are normal, with a reading of 7.48, within the normal range of 0.27-4.2. The baby is 20 days old, and the doctor has prescribed three boxes of Vitamin AD drops for home observation, with a follow-up test scheduled in three weeks.
Answer
Newborns have a vigorous metabolism, so their thyroid hormone levels may be higher than those of adults. Since the T3T4 levels are now normal, it is not necessarily abnormal. It is recommended to follow the doctor’s instructions and observe for 1-2 months before retesting the thyroid function panel. If the T3T4 levels remain normal or slightly elevated, and the thyroid hormone level decreases, it is considered normal. If not, there may be hypothyroidism, and treatment should be sought promptly. Wishing the baby a healthy growth!
