Hypothyroidism
A physical examination may reveal a smaller-than-normal thyroid gland, although sometimes the gland is normal size or even enlarged (goiter. The examination may also reveal: Brittle nails; Coarse facial features; Pale or dry skin, which may be coo...

Hypothyroidism
In the United States, newborn infants between 24 and 72 hours old are tested for congenital thyroid deficiency (cretinism) using a test that measures the levels of thyroxine in the infant's blood. If the levels are low, the physician will likely r...

Specific Tests Articles

Physical examination
During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

Thyroid Function Tests
Thyroid function tests are blood tests used to evaluate how effectively the thyroid gland is working. These tests include the thyroid-stimulating hormone test (TSH), the thyroxine test (T 4 ), the triiodothyronine test (T 3 ), the thyroxine-binding globulin test (TBG), the triiodothyro-nine resin uptake test (T 3 RU), and the long-acting thyroid stimulator test (LATS).

Thyroid Function Tests
Thyroid function tests are blood tests used to evaluate how effectively the thyroid gland is working. These tests include the thyroid-stimulating hormone test (TSH), free and total thyroxine tests (FT 4 ,T 4 ), the free and total triiodothyronine tests (FT 3 ,T 3 ), the thyroxine-binding globulin test (TBG), and the T-uptake test.

Thyroid Function Tests
The key tests to determine thyroid function are serum measurements of free thyroid hormones and thyroid-stimulating hormone (TSH). Thyroid hormones have a negative feedback on TSH secretion from the anterior pituitary. In hyperthyroidism, free thyroid hormones are increased above the normal range and TSH levels are markedly decreased. In hypothyroidism, free thyroid hormones are decreased and TSH concentrations are increased when the cause is disease of the thyroid gland; when caused by a deficiency of TSH, free thyroid hormones are decreased but TSH is usually low. Radioactive iodine studies of the thyroid gland, which used to be the mainstay of testing, have been supplanted by these blood tests. M ARTIN I.

TSH
TSH is a laboratory test that measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland and tells the thyroid gland to make and release the hormones thyroxine (T4) and triiodothyronine (T3. See also: T3 test; T4 test.

T4 test
T4 (thyroxine) is a hormone produced by the thyroid gland. A laboratory test can be done to measure the amount of T4 in your blood.

T3
Triiodothyronine (T3) is a thyroid hormone. It plays an important role in the body's control of metabolism. A laboratory test can be done to measure the amount of T3 in your blood. See also: T4 test; TSH test.

Antithyroid microsomal antibody
Antithyroid microsomal antibody is a test to measure antithyroid microsomal antibodies in the blood. Microsomes are found inside thyroid cells. The body produces antibodies to microsomes when there has been damage to thyroid cells.
