Diagnostics - Thyroid Testing

Question 1

What does standard thyroid testing typically measure?

Answer 1

Standard testing typically measures TSH (Thyroid Stimulating Hormone) and T4 (Thyroxine) levels.

Question 2

What additional tests might be included in expanded thyroid panels?

Answer 2

Expanded panels may include Free T3, Free T4, Reverse T3, and thyroid antibodies (anti-TPO and anti-thyroglobulin).

Question 3

What is subclinical hypothyroidism?

Answer 3

Subclinical hypothyroidism is a condition where individuals have normal thyroid hormone levels but may still exhibit symptoms of poor thyroid function, often indicated by high TSH levels.

Question 4

What does a high TSH level with normal T4 indicate?

Answer 4

A high TSH level with normal T4 indicates possible subclinical hypothyroidism, which warrants further comprehensive testing, especially for thyroid antibodies.

Question 5

Why might a person with normal thyroid hormone levels still have symptoms?

Answer 5

They may have normal readings near the reference range but experience symptoms of thyroid dysfunction, indicating a need for further evaluation.
