Dr. Jolly's Thyroid Panel
Fasting Required: No

Specimen: Blood

Results: 3-5 Business Days

Tests Included:

Free T3: This test is used to evaluate thyroid function. It is primarily used to diagnose hyperthyroidism. It is also used to assess abnormal binding protein disorders and to monitor thyroid replacement and suppressive therapy .

Free T4: This test is used to evaluate thyroid function in individuals who may have protein abnormalities that could affect total T4 levels. It is used to evaluate thyroid function and monitor replacement and suppressive therapy.

TSH: The best way to initially test thyroid function is to measure the TSH level in a blood sample. A high TSH level indicates that the thyroid gland is failing because of a problem that is directly affecting the thyroid (primary hypothyroidism). The opposite situation, in which the TSH level is low, usually indicates that the person has an overactive thyroid that is producing too much thyroid hormone (hyperthyroidism). Occasionally, a low TSH may resyult from an abnormality in the pituitary gland, which prevents it from making enought TSH to stimulate the thyroid (secondary hypothyroidism). In most healthy individuals, a normal TSH value means that the thyroid is functioning normally.

TPO: The TPO gene provides instructions for making an enzyme called thyroid peroxidase. This enzyme plays a central role in the function of the thyroid gland. Thyroid peroxidase assists the chemical reaction that adds iodine to a protein called thyroglobulin, a critical step in generating thyroid hormones. Thyroid hormones play an important role in regulating growth, brain development, and the rate of chemical reactions in the body (metabolism).

Reverse T3: Reverse-T3 does not stimulate metabolism. It is produced as a way to help clear some T4 from the body.

Ferritin: Composed of iron and protein, Ferritin is a storehouse for iron in the body. Measurement provides an accurate picture of how much iron you have available in reserve. It is used to evaluate anemia and for diagnosing iron deficiency. Low Ferritin is a sign of iron deficiency. Ferritin is high with inflammation, infection, liver disease, iron overload, certain anemias and certain cancers (leukemia and lymphoma).
