What does TSH evaluate?

• A. Thyroid function
• B. Kidney function
• C. Liver function
• D. Adrenal function

Answer: (A)

TSH evaluates thyroid function. It’s a pituitary hormone that stimulates the thyroid to make thyroid hormones (T4 and T3). Because of negative feedback, TSH levels rise when thyroid hormone levels are low and fall when they’re high. So a high TSH points to hypothyroidism, and a low TSH points to hyperthyroidism or a pituitary issue. This test is widely used for screening and for monitoring thyroid treatment. It does not measure kidney, liver, or adrenal function, which require other tests.
