Thyroid tests are blood tests used to evaluate the function of the thyroid gland, which is responsible for producing hormones that regulate metabolism, growth, and energy levels. These tests are performed to diagnose thyroid disorders such as:
- hypothyroidism (underactive thyroid)
- hyperthyroidism (overactive thyroid)
- thyroid nodules
- thyroid cancer
They help assess thyroid hormone levels and thyroid gland function to guide treatment and management decisions.
