Tests Included:

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

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.

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).

TSH: Used to diagnose a thyroid disorder in a person with symptoms, screen newborns for an underactive thyroid, monitor thyroid replacement therapy in people with hypothyroidism, diagnose and monitor female infertility problems, help evaluate the function of the pituitary gland (occasionally), and screen adults for thyroid disorders, although expert opinions vary on who can benefit from screening and at what age to begin.

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).

Vitamin D, 25-Hydroxy: This highly automated test measures both D2 and D3 together and reports a total 25-hydroxyl.

Vitamin D is also known as the "sunshine vitamin" because the body manufactures the vitamin after being exposed to sunshine. Ten to 15 minutes of sunshine 3 times weekly is enough to produce the body's requirement of vitamin D. Needed for strong bones and teeth, Vitamin D helps your body absorb the amount of calcium it needs. It also has other roles in the body, including modulation of cell growth, neuromuscular and immune function, and reduction of inflammation. There are associations between low Vitamin D levels and peripheral vascular disease, certain cancers, multiple sclerosis, rheumatoid arthritis, juvenile diabetes, Parkinson's, and Alzheimer's disease.
