Thyroid Health Screening

Thyroid function tests include measurement of the levels of

Thyroid stimulating hormone (TSH)

Free thyroxine (FT4) and
Free triiodothyronine (FT3)

Their measurements are used to test for thyroid dysfunction, including its underactivity (hypothyroidism) and overactivity (hyperthyroidism).

Additional thyroid antibodies tests may be performed as a follow-up when the thyroid test results of fT4, and/or TSH show signs of thyroid dysfunction. Occasionally, these tests are performed if a person with a known autoimmune condition, such as systemic lupus erythematosus or rheumatoid arthritis develops symptoms suggestive of thyroid disease. These thyroid antibodies tests help differentiate different types of thyroiditis and identify autoimmune thyroid conditions. These antibodies include:

  • Thyroid peroxidase (TPO) antibody
  • Thyroglobulin (TG) antibody
  • Thyroid stimulating hormone receptor (TSHR) antibodies

These tests are offered at an extra cost, please contact us for more information.

The thyroid is a gland at the base of our throat. The cells of this gland absorb iodine which is used to produce the hormones thyroxine (T4) and tri-iodothyronine (T3). Both are involved in the metabolism in our body. Most of T3 and T4 are bound to proteins, their biologically active form is unbound or free. The measurement of the free form is preferred as is not dependent on a number of proteins in the blood.

The thyroid gland is under the control of the pituitary gland located in our brain. Therefore, the production of T3 and T4 is regulated by the thyroid stimulating hormone (TSH) which is produced in the pituitary gland. In addition, the pituitary gland is regulated by another gland in the brain, called the hypothalamus, through the production of the TSH Releasing Hormone (TRH).

Thyroid diseases are conditions that affect a number of thyroid hormones being produced. Changes in the thyroid function affect your energy level, your heart rate, your weight, your mood, your bowel movement, your skin and more. Disorders of the thyroid are among the most prevalent in the population and are estimated to affect more than 5% of the people. The risk for these chronic endocrine conditions increases with age and women are more likely to suffer thyroid disorders.

Test type: Blood

Fasting is not required for the blood test. Drink plenty of water before the blood drawing as being well hydrated makes the blood drawing procedure easier.

When you need to get your thyroid function tests done, it is advisable to do so prior to taking your thyroid replacement therapy (such as Levothyroxine or Armour Thyroid). For example, first thing in the morning bringing your medications with you to take after your bloods have been taken. This will ensure that you get accurate test results. The same advice applies if you take the diuretic furosemide.

A small amount of blood will be drawn by trained staff from a vein in your arm using a needle. The procedure is quick and easy. Rarely, some people may feel faint or dizzy while having the blood taken and you may need to lie down to help you to feel better. The procedure may cause some minor discomfort and a small bruise may develop in the area where the needle was inserted. Press over the site where the needle was inserted, keeping your arm straight to reduce the likelihood of bruise formation. If you develop redness or inflammation in the same area, seek your doctor for advice.

A laboratory test result is produced after a scientific analysis done on a sample to assess an individual health status.

An abnormal finding may (but not necessarily) indicate a problem that needs to be addressed. We recommend that any abnormal result should promptly be consulted with your GP. Your doctor will evaluate the test results in the context of an overall clinical picture that takes into consideration your age, gender, ethnicity, family history, signs, symptoms, etc.

If you want to learn more how the results of your laboratory test help your doctor in understanding your health status, and in providing you with the right treatment; check http://labtestsonline.org, a public resource on lab tests that is produced by AACC, a global scientific and medical professional organization dedicated to clinical laboratory science and its application to healthcare. You can also visit http://patient.info for information about health conditions. Please note that this information should not be a substitute for a consultation with your doctor.

Please contact us, we will be happy to clarify any questions pertaining to your test results.
