Your thyroid, a small butterfly-shaped gland in your neck, plays a big role in your health. It produces hormones that regulate metabolism, energy levels, body temperature, and even mood. When your thyroid isn’t functioning correctly, it can lead to a range of symptoms. That’s where thyroid panel tests come in.
At Life Quest Diagnostics, we offer comprehensive thyroid testing to help you understand your thyroid health and get the care you need.
Why are Thyroid Tests Important?
Thyroid disorders, such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), can be difficult to diagnose based on symptoms alone. These symptoms can mimic other health issues. Thyroid panel tests provide crucial information to help doctors accurately diagnose thyroid conditions and develop appropriate treatment plans. Early detection and management of thyroid problems are essential for preventing long-term health complications.
What is a Thyroid Panel?
A thyroid panel is a group of blood tests that measure different thyroid hormone levels. These tests work together to give a comprehensive picture of your thyroid function. A typical thyroid panel includes:
- TSH (Thyroid-Stimulating Hormone): This is often the first test done. TSH is produced by the pituitary gland and tells the thyroid how much hormone to make. High TSH usually means an underactive thyroid (hypothyroidism), while low TSH often indicates an overactive thyroid (hyperthyroidism).
- T4 (Thyroxine): This is the inactive form of thyroid hormone. The thyroid produces mostly T4, which is then converted to T3.
- T3 (Triiodothyronine): This is the active form of thyroid hormone. T3 is much more potent than T4 and directly affects your metabolism.
Sometimes, depending on your specific situation, your doctor may also order additional thyroid tests, such as:
- Free T4 and Free T3: These tests measure the unbound, active forms of T4 and T3, which are more readily available to your cells.
- Reverse T3: This is an inactive form of T3. Its role in thyroid function is still being researched.
- Thyroid Antibodies: These tests check for antibodies that attack the thyroid gland, which can indicate autoimmune thyroid diseases like Hashimoto’s thyroiditis (hypothyroidism) or Graves’ disease (hyperthyroidism).
Who Should Get a Thyroid Test?
Thyroid testing is recommended for individuals experiencing symptoms suggestive of a thyroid disorder. These symptoms can be varied and may include:
- Hypothyroidism (Underactive Thyroid): Fatigue, weight gain, constipation, dry skin, hair loss, feeling cold, muscle weakness, depression, and memory problems.
- Hyperthyroidism (Overactive Thyroid): Weight loss, rapid heartbeat, anxiety, irritability, tremors, sweating, difficulty sleeping, and eye problems.
In addition to those with symptoms, certain groups are at higher risk for thyroid problems and may benefit from routine screening, including:
- Women over the age of 35
- People with a family history of thyroid disease
- Individuals with autoimmune disorders
- Pregnant women or women who have recently given birth
