Question
When checking for the cause of precocious puberty, the doctor measured T4 and TSH levels, as well as sex hormone levels, but the results are to be awaited until next week. Currently, it has been found that the TSH level is 4.36, slightly higher than the normal range. What does this mean? Is it necessary to undergo a CT scan or MRI of the brain?
Answer
At present, the TSH level is only slightly elevated. In this case, there is no need for additional tests, such as a brain CT. As long as there are no other special symptoms and thyroid hormone levels are normal, this does not indicate an abnormality. A high TSH may suggest thyroid dysfunction, but with normal T4 levels. Whether further examination is needed should be analyzed based on the results of the sex hormone test.
