What are thyroid function tests?

Thyroid function tests are a series of blood tests used to measure how well your thyroid gland is working. Available tests include the T3, T3RU, T4, and TSH.The thyroid is a small gland located in the lower-front part of your neck. It’s responsible for helping to regulate many of the body’s processes, such as metabolism, energy generation, and mood.The thyroid produces two major hormones: triiodothyronine (T3) and thyroxine (T4). If your thyroid gland doesn’t produce enough of these hormones, you may experience symptoms such as weight gain, lack of energy, and depression. This condition is called hypothyroidism.If your thyroid gland produces too many hormones, you may experience weight loss, high levels of anxiety, tremors, and a sense of being on a high. This is called hyperthyroidism.

Typically, a doctor who is concerned about your thyroid hormone levels will order broad screening tests, such as the T4 or the thyroid-stimulating hormone (TSH) test. If those results come back abnormal, your doctor will order further tests to pinpoint the reason for the problem.

The technician will then place a small bandage over the wound.T4 and TSH results
The T4 test and the TSH test are the two most common thyroid function tests. They’re usually ordered together.

The T4 test is known as the thyroxine test. A high level of T4 indicates an overactive thyroid (hyperthyroidism). Symptoms include anxiety, unplanned weight loss, tremors, and diarrhea. Most of the T4 in your body is bound to protein. A small portion of T4 is not and this is called free T4. Free T4 is the form that is readily available for your body to use. Sometimes a free T4 level is also checked along with the T4 test.

The TSH test measures the level of thyroid-stimulating hormone in your blood. The TSH has a normal test range between 0.4 and 4.0 milli-international units of hormone per liter of blood (mIU/L).

If you show signs of hypothyroidism and have a TSH reading above 2.0 mIU/L, you’re at risk for progressing to hypothyroidism. Symptoms include weight gain, fatigue, depression, and brittle hair and fingernails. Your doctor will likely want to perform thyroid function tests at least every other year going forward. Your doctor may also decide to begin treating you with medications, such as levothyroxine, to ease your symptoms.Both the T4 and TSH tests are routinely performed on newborn babies to identify a low-functioning thyroid gland. If left untreated, this condition, called congenital hypothyroidism, can lead to developmental disabilities.

T3 results
The T3 test checks for levels of the hormone triiodothyronine. It’s usually ordered if T4 tests and TSH tests suggest hyperthyroidism. The T3 test may also be ordered if you’re showing signs of an overactive thyroid gland and your T4 and TSH aren’t elevatedTrusted Source.

The normal range for the T3 is 100–200 nanograms of hormone per deciliter of blood (ng/dL). Abnormally high levels most commonly indicate a condition called Grave’s disease. This is an autoimmune disorder associated with hyperthyroidism.

Overall,Thyroid organ is a butterfly formed organ situated at the base of the neck. Besides, the organ produces hormones, for example, triiodothyronine (T3), and thyroxine (T4). Also, these hormones are mindful underway and guideline of the hormones, for example, adrenaline and dopamine. In addition, adrenaline and dopamine assume a significant job in passionate reactions, for example, dread, energy, and joy. What's more, hormones from this organ likewise help the guideline of digestion. Henceforth, the underproduction, and overproduction of these hormones can lead genuine wellbeing disintegrations. In this manner, the testing of the degree of these hormones in the body is exceptionally basic. Thyroid capacity test includes arrangement of blood tests used to quantify ampleness of the degrees of thyroid hormones. These blood tests can characterize whether the thyroid hormone creation is typical, overactive, or underactive. It includes the various kinds of test, for example, T3, T4, TSH, and T3RU. Also, these tests are directed in symptomatic research facilities which are outfitted with instruments which are utilized by clinical experts to complete these tests. Moreover, these tests are additionally completed in clinics where thyroid related ailments are analyzed by authorities. 

The worldwide thyroid capacity test showcase is relied upon to display critical development during the gauge time frame, attributable to increment in pervasiveness of thyroid issue. For example, roughly, 20 million Americans are experiencing some type of thyroid illness, and up to 60% of those with thyroid infection are ignorant of their condition. What's more, calculates, for example, increment mindfulness for early screening of infection, and nearness of cutting edge symptomatic research facilities additionally fuel the development of thyroid capacity test advertise.
