Thyroid Test : Weird 2009 Story
The thyroid gland is located in the neck area and has a butterfly shape. The most common forms of thyroid disorder are symptoms which make people too tall or very short, too thin or very fat.The gland produces four hormones most essential for the body to assimilate and eliminate all the substances that enter the body.
High thyroid levels or hyperthyroidism causes a series of effects that need medical treatment. Patient’s whit this condition may have insomnia that are slightly different from common sleeping disorders. A regular insomnia sufferer has troubles getting to sleep, but he can sleep for most of the day.
This hormone is responsible for the metabolic processes that occur inside the body, such as food assimilation or the replacement of the sleeping hormone.
Because of the accelerated metabolism, the patient does not assimilate fat as it suppose to and eliminates most of the vital substances needed, thus resulting in a small weight.
Rapid heart beats or tachycardia is also linked to a thyroid that is over active. Hormones in the body need to be in the proper quantity for the organism to function well.Low levels of hormones secreted by the thyroid have the opposed side effects.
Although symptoms may be similar, there is a big difference in hypothyroidism. Because the hormones can no longer keep the metabolism going as it should, the patient gains a lot of weight fast. Problems with falling asleep are also encountered, and though people with hyperthyroidism feel overactive, those with hypothyroidism might feel tired all the time, no matter how much they sleep.
There are many aspects to look at when it comes to the thyroid. Blood tests are the most reliable and accurate method used to evaluate thyroid function. A thyroid blood test or a thyroid panel should contain information to determine if there is primary thyroid dysfunction, peripheral dysfunction or another gland/system which should be evaluated. A thyroid blood test should contain the following:
Thyroid stimulating hormone is produced by the pituitary gland which signals the thyroid to produce more T4. TSH can be used to determine primary hypothyroidism but cannot be used alone when screening for secondary hypothyroidism. Even though TSH is a helpful tool in screening, the amount of TSH suppression does not always show the severity of hyperthyroidism.
TSH levels can be affected by several prescription medications including glucocorticoids-like prednisone and dopamine-found in certain anti-depressants.
By using TSH to assess thyroid function, you are assuming that the thyroid-hypothalamus-pituitary triangle is functioning properly.
T4 is the major hormone produced and secreted by the thyroid gland.
An indirect measurement of thyroid binding globulin (TBG). This measures the binding sites on the thyroid proteins which are unsaturated. This is looked at if there is a high Total T4. If total T4 and T3 uptake are abnormal and inversely proportional it is due to changes in binding capacity, if not it shows a secondary change in thyroid function.
