The Basic Thyroid Panel is a commonly ordered blood test that evaluates how the thyroid gland is functioning and is used in the diagnosis of hyper- and hypothyroidism.

It can also suggest important information about the function of other endocrine glands such as the pituitary. The thyroid gland helps regulate the body’s use of energy and keeps the heart, muscles, and other vital organs working properly.

It measures the following:

• Thyroid-stimulating hormone (TSH)
• Triiodothyronine (T3) Free
• Thyroxine (T4) Free
• Thyroxine (T4) Total
• Triiodothyronine (T3) Total
