Types of Thyroid Lab Tests
Laboratory Tests. The first test a health practitioner will usually order to detect thyroid dysfunction is a test for thyroid stimulating hormone (TSH) . If the TSH level is abnormal, the health practitioner will usually order a test for free thyroxine (free T4) to confirm the diagnosis. Tests. Laboratory Tests.

If the TSH level is abnormal, the health practitioner will usually order a test for free thyroxine (free T4) to confirm the diagnosis. The three types of thyroid blood tests are the total thyroxine test, the free thyroxine test and the triiodothyronine test. Each of these tests can determine whether the thyroid is releasing the appropriate number of hormones in the body. Thyroid function tests are blood tests which help to check the function of the thyroid gland. They are mainly used to detect hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). Note: the information below is a general guide only. There are several types of imaging tests performed for diagnosis of various thyroid conditions. These tests include: 1  Thyroid Ultrasound – commonly used to evaluate nodules, lumps and enlargement of your thyroid gland. 2  Ultrasound can tell whether a nodule is a fluid-filled cyst, or a mass of solid tissue. These tests may help doctors to find a specific cause of the low TSH. Thyroid function tests are usually done to find out whether the thyroid gland is working properly. This is mainly to diagnose underactive thyroid (hypothyroidism) and overactive thyroid (hyperthyroidism). If the blood tests determine high hormone levels in the thyroid, it can be an indication of a goiter, abnormal growths or nodules on the thyroid, Graves’ disease or thyroiditis. Low levels of thyroid hormones can indicate pituitary disease, thyroiditis or damage to the thyroid from surgery.
