Thyroid disorders are abnormal functions of the thyroid gland. Hypothyroidism and hyperthyroidism are types of thyroid disorders, affecting women older than 60 years more than men with a rate of 24%.1 People who suffer from thyroid disorders experience many symptoms such as a high blood pressure, development of a goiter, and muscle aches. Undiagnosed thyroid disorders people who unknowingly have one of thyroid disorders are approximately 43%, which indicates a high number of people who may experience severe symptoms.2 So, early diagnosis of thyroid dysfunctions can help a doctor to treat these disorders in early stages by using an appropriate medication. Diagnosing thyroid disorders is a process that incorporates many factors including clinical …show more content…
There are three types of thyroid function tests. First, measuring the thyroid stimulating hormone(TSH) level.6 (TSH) is produced by the pituitary gland and stimulates the thyroid gland to release hormones into blood. The normal (TSH) range is from 0.4 -4.0 milli-international units per liter (mIU/L), so the result of (TSH) test that shows a higher rate of this range is considered to be a hypothyroidism disorder and a lower rate is considered to be a hyperthyroidism.7 The second test is the measuring of bounded protein hormone (TT4), which is also known as thyroxin. (TT4) has an essential role in the growth and metabolism function. The normal range of TT4 is between 4.5 to 11.2 mcg/dL (micrograms per deciliter).8 Thus, the high (TT4) level may point to hyperthyroidism, and the low level of( TT4) may point to hypothyroidism. The last test is measuring Triiodothyronine (T3) which is a thyroid hormone that controls metabolic processes in the body. The normal range of (T3) is between 100 - 200 nanograms per deciliter (ng/dL).9 The result of( T3) test resembles (TT4) test which means a higher than normal is a sign of hyperthyroidism and a lower than normal is a sign of …show more content…
First, the clinical evaluation which is based on doctor's questions and the external investigation. The second step is the blood test that is used to measure levels of TSH,TT4, andT3 hormones which are secreted from the thyroid gland. Finally, the radioactive iodine uptake test that is based on measuring the iodine absorbing by the thyroid gland. Thus, in order to prevent the development of thyroid disorders to critical conditions, it is essential for people to periodically see a doctor because the early detection of thyroid disorders improve the overall cure
