Description:
Thyroid Ultimate Panel
This package contains a variety of tests to conduct a thorough analysis of a person's thyroid function. The thyroid is a butterfly-shaped gland located in the neck below the adam's apple. Hormones produced by the thyroid play an important role in a number of bodily processes including metabolism, growth, brain development, and body temperature. An over or underactive thyroid can cause a number of health complications. Symptoms of an underactive thyroid (hypothyroidism) include fatigue, dry skin, weight gain, constipation, muscle weakness, pain or swelling in the joints, irregular menstrual periods, hair loss, lowered heart rate, impaired memory, and depression. An overactive thyroid (hyperthyroidism) can cause symptoms such as unexplained weight loss, rapid heartbeat, nervousness, anxiety, tremors, sweating, changes in menstrual patterns, fatigue, difficulty sleeping, and muscle weakness. In addition to evaluating thyroid function, the tests in this panel can help to determine if someone has an autoimmune disorder that is affecting their thyroid.
This package includes the following tests:
- TSH (Thyroid Stimulating Hormone): Produced by the pituitary gland, TSH stimulates the thyroid to produce hormones such as T4 and T3.
- T4 (Thyroxine): T4 is the primary hormone produced by the thyroid gland.
- T3 Uptake: Measures the level of proteins that help to carry thyroid hormones through the blood.
- Free Thyroxine Index: A measurement to help determine if the body is able to properly utilize T4.
- Free T3: T3 is the other major hormone produced by the thyroid. Free T3 is the unbound biologically active form of the hormone.
- Free T4: Measuring the unbound or free level of T4 is often considered more accurate than total T4.
- Reverse T3: High levels of inactive or reverse T3 are often a sign of hypothyroidism.
- Thyroid Peroxidase Antibody (TPO): A type of autoantibody that is often present in people with autoimmune disorders such as Grave's Disease or Hashimoto's Thyroiditis.
- Thyroglobulin Antibody: Another type of autoantibody that can attack thyroid tissue.
Thyroid testing is typically ordered when someone is experiencing symptoms of thyroid dysfunction. Irregular test results should be discussed with your doctor to determine the appropriate follow-up. For more testing options, please see our thyroid category.
Turnaround time for this test is typically 4-8 business days.
