TestDescription of the Test
Anti-thyroid peroxidase (Anti-TPO) antibodyThe level of anti-TPO antibodies is increased in autoimmune diseases affecting the thyroid such as Graves disease and Hashimoto’s thyroiditis. It may also be high in patients suffering from other autoimmune disorders such as rheumatoid arthritis and type 1 diabetes.
Thyroid stimulating hormone (TSH)The thyroid stimulating hormone (TSH) is secreted by a gland called the pituitary gland. It controls the release of thyroid hormone from the thyroid gland. Its level is often measured to screen for thyroid disorders.
Total T3, free T3T3 is a hormone that is released by the thyroid gland. Low levels indicate hypothyroidism, while high levels indicate hyperthyroidism. Free T3 is the active form of the hormone, and therefore free T3 levels may give a more accurate picture of the thyroid disease.
Total T4, free T4T4 is a hormone that is released by the thyroid gland. Low levels indicate hypothyroidism, while high levels indicate hyperthyroidism. Free T4 is the active form of the hormone, and therefore free T4 levels may give a more accurate picture of the thyroid disease.
TSH receptor antibodyThe level of TSH receptor antibodies is increased in autoimmune diseases affecting the thyroid such as Graves disease and Hashimoto’s thyroiditis. It may also be high in patients suffering from other autoimmune disorders such as rheumatoid arthritis and type 1 diabetes.
