WHY SHOULD YOU GET TESTED FOR YOUR THYROID FUNCTION?
Thyroid problems are on the rise among Indians: Around 40 million people in the country are estimated to suffer from thyroid related disorders, of which 60 per cent are women. However, because the initial signs and symptoms are vague and ambiguous, thyroid disease is often missed in its early stages. Patients may be treated instead for infertility, high cholesterol, anaemia or depression.
The reality is that thyroid disease has complex causes. This arises as a result of a combination of environmental, nutritional and lifestyle factors. Everyone should be screened for thyroid dysfunction every 5 years, beginning at age 35, according to the American Thyroid Association. People with symptoms or risk factors may need tests more often.
WHAT ARE T3, T4 TSH TESTS?
The thyroid gland produces two hormones – thyroxine (T4) and triiodothyronine (T3), both of which play a vital role in keeping our mind and body healthy. The production of these hormones is regulated by another hormone called the Thyroid Stimulating Hormone (TSH).
1. These hormones regulate heat production in our body and also contribute to the health of the heart and cardiovascular system, helping to regulate blood pressure and fats such as cholesterol and triglycerides.
2. They regulate the growth and development of tissue and are essential for the normal development of the nervous and reproductive systems.
3. In addition, they play a role in regulating female hormones influencing the menstrual cycle, fertility and the ability to carry a pregnancy to full term.
WHAT IS THE DIFFERENCE BETWEEN T3 AND FREE T3?
Triiodothyronine (T3) is a thyroid hormone that circulates in blood almost completely bound (99.5%) to carrier proteins. The main transport protein is thyroxine-binding globulin (TBG). However, only the free (unbound) portion of triiodothyronine (free T3) is believed to be responsible for the biological action. Furthermore, the concentrations of the carrier proteins are altered in many clinical conditions, such as pregnancy.
In normal thyroid function, as the concentrations of the carrier proteins changes, the total triiodothyronine level also changes, so that the free triiodothyronine concentration remains constant. (In an abnormally functioning thyroid, this is not necessarily so). Measurements of free triiodothyronine (Free T3) concentrations, therefore, correlate more reliably with your clinical status than total triiodothyronine (T3) levels.
For example, the increase in total triiodothyronine levels associated with pregnancy, oral contraceptives and estrogen therapy result in higher total T3 levels while the free T3 concentration remains unchanged (in normal individuals).
WHAT IS FREE T4 (FT4)?
The level of free T4 hormone illustrates how much is immediately available for uptake and use by cells, and measure of free T3 hormone in the body is considered a more accurate view of hormonal balance than a total T3 reading.
