Diagnosing the Thyroid

Disorders of the thyroid gland are the most common problems encountered by people in the young and middle adulthood. Women have a higher incidence rate for thyroid disorders. The problems experienced by people with thyroid gland disorders can be really life-threatening so early and appropriate interventions should be given. The appropriate diagnostic tests are essential for proper diagnosis of the disease.

Diagnostic Tests for your Thyroid Gland

Blood Test: The test needed to determine if your thyroid has any deviations or performing normally is through blood test. The Serum T3 or triiodothyroxine as well as T4 or thyroxine is the indicators for any disorders of the thyroid. If the T3 and T4 level are low, then a person may be diagnosed of hypothyroidism. On the other hand, if the thyroxine levels are high, then a person may be experiencing hyperthyroidism or Grave’s disease. To determine if thyroid cancer is a concern, the thyroglobulin for follicular adenocarcinoma can become markers for the disease.

Ultrasound: Another diagnostic test is the ultrasound. It is used to determine the structure and consistency of the thyroid gland. They are essential to determine if the nodules of the thyroid are benign or malignant. The ultrasonic waves of the machine produce a highly defined picture of the thyroid gland. To consider a thyroid gland as benign, it should have smooth borders and hyperechoic (more echogenic than the surrounding tissues). On the other hand, a nodule is malignant if it has irregular borders, hypoechoic (less echogenic than the surrounding tissues), microcalcifications or the formation of calcium deposits in the nodules and significant intranodular blood flow. But ultrasound is not considered as a reliable source to determine the existence of cancer. It can be used for the determination of the enlargement of the thyroid.

Radioactive Scanning: A more accurate means to determine disorders of the thyroid is the radioactive scanning and uptake. The radioactive scanning is performed with the use of a radioactive iodine medium. This radioactive medium collects or stays in the thyroid gland before it is excreted in the urine. With the use of the radioactive scanning, you can determine the shape and the activity of your thyroid gland. An abnormality in the gland may be seen through the irregularity of the uptake as well as the location of the gland. For instance, if a portion of the gland is overactive causing to inhibit the actions of the rest of the glands, this could be diagnosed as an adenoma. This disorder can easily be prevented through surgery. On the other hand, if the gland is under active. This may be diagnosed as thyroid cancer because a part of the gland ceases to function normally. The radioactivity exhibited by the gland will determine or serve as an indicator of the metabolic capacity of the gland. The radioactive uptake demonstrates 8 to 35 percent of the gland’s activity. It can determine with 24 hours after administration of radioiodine. If the uptake is low, it can predispose to hypothyroidism. If it is high, this can be diagnosed as hyperthyroidism.

For those who have are at risk of having thyroid cancers, you can submit to biopsy to determine if the nodules of your thyroid gland are benign or malignant.

These are the diagnostic test you can use to determine if your thyroid gland is in its optimal condition or not. “Prevention is better than cure!” so you should take good care of your body. Eat the right kind and amount of foods daily, perform exercises and control all your stresses in life. These things may contribute to a healthier living and may prevent any foreseeable crises that may arise.
