Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid.
<br>
<br>A TFT panel typically includes thyroid-stimulating hormone (TSH, thyrotropin) and thyroxine (T4), and triiodothyronine (T3) depending on local laboratory policy.
<br>
<br>TFTs may be requested if a patient is thought to suffer from hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thryoid), or to monitor the effectiveness of either thyroid-suppression or hormone replacement therapy. It is also requested routinely in conditions linked to thyroid disease, such as atrial fibrillation.
<br>
<br>The thyroid hormones, thyroxine (T4) and triiodothyronine (T3), are tyrosine-based hormones produced by the thyroid gland. An important component in the synthesis is iodine. The major form of thyroid hormone in the blood is thyroxine (T4). The ratio of T4 to T3 released in the blood is roughly 20 to 1. Thyroxine is converted to the active T3 (three to four times more potent than T4) within cells by deiodinases (5'-iodinase). These are further processed by decarboxylation and deiodination to produce iodothyronamine (T1a) and thyronamine (T0a). |

Iodized salt is table salt mixed with a minute amount of iodide salts to help reduce the chance of iodine deficiency, which can lead to thyroid gland problems, the most common being goiter. Only tiny quantities of iodine are required in a diet to prevent this disease, but there are many places around the world where natural levels of iodine in the soil are low and the iodine is not taken up by vegetables.
<br>
<br>Iodized salt is a cheap and effective way of distributing the vital element. Iodized salt is more common in the United States, Australia and New Zealand than Britain, where iodised milk is more popular.
<br>
<br>The United States Food and Drug Administration recommends (21 CFR 101.9 (c)(8)(iv)) 150 micrograms of iodine per day for both men and women

<br>Table salt
<br>
<br>Single-serving salt packetsTable salt is refined salt, nearly pure (95% or greater) sodium chloride. It usually contains substances that make it free flowing (anticaking agents) such as sodium silicoaluminate as well as a minute amount of invert sugar to prevent the salt from turning a yellow colour when exposed to sunlight, and to prevent a significant loss of iodine via vaporization. It is common practice to put a few grains of uncooked rice in salt shakers to absorb extra moisture when anticaking agents are not enough. Table salt is also often iodised—a small amount of potassium iodide (in the US) or potassium iodate (in the EU) is added as an important dietary supplement. Table salt is mainly employed in cooking and as a table condiment. Iodised table salt has significantly reduced disorders of iodine deficiency in countries where it is used. Iodine is important to prevent the insufficient production of thyroid hormones (hypothyroidism), which can cause goitre, cretinism in children, and myxedema in adults.
<br>
<br>Table salt is now used all over the world.
<br>
<br>In European countries where fluoridation of drinking water is not practiced, some brands of fluorinated and iodised table salt are available. In Germany, 60% of sold table salt contains sodium or potassium fluoride. Another additive, especially important for pregnant women is Folic acid (B vitamin) giving the table salt a yellow color.

<br>Is iodized salt available in your area? |
