What is the thyroid profile test?
A thyroid profile test helps to assess whether your thyroid gland is operating properly, helps to detect any thyroid disorder, and also helps doctors examine the workfulness of thyroid treatment.
Thyroid test aids to detect thyroid disorders including:
- Hyperthyroidism: Hyperthyroidism is known as overactive thyroid, in which your thyroid gland produces too much of thyroid hormones than your body’s need. Hyperthyroidism induces your metabolism to speed up, which causes hyperthyroidism patients to lose weight, rapid heart rate, puffiness and other issues.
- Hypothyroidism: Hypothyroidism is known as underactive thyroid, in which your thyroid gland does not create enough thyroid hormones as per your body’s need. Underactive thyroid slows down your metabolism, for which you may gain more weight, you may experience irregular menstrual, fatigue, and so many other issues.
- Thyroiditis: Inflammation or swelling of the thyroid gland is considered as thyroiditis. Later on thyroiditis can damage your thyroid hormone production, which may contribute to hyperthyroidism and hypothyroidism. Symptoms of thyroiditis will depend on the severity of your thyroiditis.
- Thyroid cancer: Thyroid cancer is one of the types of endocrine cancer. Thyroid cancer is very much treatable, but also a number of people die with thyroid cancer each year.
- Thyroid nodules: thyroid nodules occur when a lump develops in your thyroid gland. This lump can be solid or fluid-filled. Thyroid nodules may not show symptoms, and thyroid nodules are rarely cancerous.
- Hashimotos’s disease: Hashimoto’s disease is also called chronic lymphocytic thyroiditis, occurs when your immune system accidentally attacks your thyroid gland. This may cause severe inflammation in the thyroid gland. Later on Hashimoto’s disease can also be the reason for hypothyroidism and hyperthyroidism.
- Grave’s disease: Graves’s disease is also called basedow's disease, which is an immune system disorder, and is more common in women aged over 40 than men. Grave’s disease is one of the reasons for hyperthyroidism.
- Goiter: The abnormal growth of your thyroid gland is called goiter. Iodine deficiency may cause goiter. Generally, goiter does not show many symptoms, you may experience swelling, and tightness of breath.
What is being tested in a thyroid profile?
A thyroid profile test is a combination of several groups of thyroid tests, which aids to evaluate your thyroid galnd’s function, and also helps to detect several thyroid disorders. A thyroid profile incorporates tests for:
- Thyroid stimulating hormones(TSH): Your pituitary gland secretes thyroid stimulating hormone, which aids to balance the other thyroid hormones including T3 and T4. Possibly, every healthcare provider asks for this test at first, as TSH hormone helps in balancing thyroid hormones. Raised TSH level indicates hypothyroidism and reduced TSH level indicates hyperthyroidism.
- Triiodothyronine (T3): Test helps to detect hyperthyroidism, and also helps to analyze the severity of your hyperthyroidism by measuring the amount of T3 in your blood. Low T3 level indicates hypothyroidism, and high T3 level indicates hyperthyroidism.
- Thyroxine (T4): Test for thyroxine hormones helps in diagnosing thyroid disorders, and helps in monitoring the usefulness of the thyroid treatment. Decreased T4 level indicates hypothyroidism, increased level of T4 indicates hyperthyroidism.
- Thyroid antibody: Anti-thyroid antibodies test helps the doctor to detect any autoimmune thyroid disorder such as graves disease, and Hashimoto's disease.

Result interpretation of thyroid profile test
The normal ranges of these thyroid hormones may differ slightly depending on your laboratory. However, here is the approximate normal ranges of the thyroid hormones:
- TSH: 0.40 - 4.50 mIU/mL
- Thyroxine (T4): 5.0 - 11.0 ug/dL
- Triiodothyronine (T3): 100 - 200 ng/dL
- Free triiodothyronine (free T3): 2.3 - 4.1 pg/mL
- Free thyroxine (free thyroxine): 0.9 - 1.7 ng/dL
Elevated TSH level can prompt the thyroid gland to produce abnormal amounts of T3 and T4, for which you may experience symptoms of hyperthyroidism. Besides, the reduced levels of thyroid hormones are associated with the symptoms of hypothyroidism.
