What Is a Thyroid Test?
A thyroid test is a blood test that evaluates the functioning of the thyroid gland by measuring important hormones including TSH, T3, and T4. The thyroid gland plays a vital role in regulating metabolism, energy production, body temperature, heart rate, and overall hormonal balance.
Abnormal thyroid hormone levels may indicate hypothyroidism, hyperthyroidism, thyroid inflammation, or other thyroid-related conditions.
