🧪 What is TSH?

Thyroid Stimulating Hormone (TSH) is a hormone produced by the pituitary gland that regulates the production of thyroid hormones T3 and T4 by the thyroid gland. It plays a key role in maintaining thyroid hormone balance and metabolic homeostasis.

❓ Why is the Test Done?

To:

Evaluate thyroid function
Diagnose hypothyroidism and hyperthyroidism
Monitor thyroid hormone replacement or antithyroid therapy
Screen newborns and adults for thyroid disorders
Investigate symptoms such as fatigue, weight changes, temperature intolerance, and mood changes
