Thyroid Stimulating Hormone Test

A Thyroid Stimulating Hormone (TSH) test measures the level of TSH in your blood, which is produced by your pituitary gland to regulate your thyroid function. The thyroid controls important processes like energy use, temperature, and growth. If TSH levels are high, it may indicate an underactive thyroid (hypothyroidism); if low, it could suggest an overactive thyroid (hyperthyroidism). This test helps diagnose thyroid disorders and guides treatment decisions. It’s a simple blood test usually performed in a healthcare setting, providing valuable information about your thyroid health.
