Thyroid Antibodies Test - Symptoms That Show You Require It

Glands are the essential organs that are located throughout our bodies. They are responsible for producing & releasing substances that perform various functions inside our body. The thyroid is one such small, butterfly-shaped gland located near the throat. It is mainly responsible for producing hormones that regulate how your body uses energy. It plays a highly essential role in regulating weight, muscle strength, body temperature, and mood.

Our immune system makes antibodies to shield the body from outer microbes and infections. At the point when dangerous things attack the body, antibodies obliterate them. But sometimes, the antibodies attack the body's cells and organs mistakenly, known as an autoimmune response. It is the main reason behind an autoimmune disorder of the thyroid.

Antithyroid antibodies target some specific parts of the thyroid gland, which mainly includes –

(1) Thyroid peroxidase (TPO) is an enzyme that plays a vital role in producing thyroid hormones. 

(2) Thyroglobulin (Tg), on the other hand, also helps the body produce thyroid hormones. 

(3) Thyroid-stimulating hormone (TSH) receptor causes the gland to make and release thyroid hormones in the blood.

These antibodies further damage the gland and affect its working.

When Do You Require a Thyroid Antibodies Test?

If you are experiencing thyroid problem symptoms and your health care provider thinks these symptoms may be due to autoimmune disorders, such as Hashimoto's disease or Graves' disease. Online pathology test booking is an easier way to get yourself checked.

Symptoms of Grave's disease include:-

  • Bulging of the eyes
  • Low tolerance for heat
  • Anxiety
  • Weight loss
  • Trouble sleeping
  • Swollen thyroid, known as goitre
  • Tremors in the hand
  • Increased heart rate

Symptoms of Hashimoto disease include:-

  • Irregular menstrual periods
  • Depression
  • Low tolerance for cold temperatures
  • Weight gain
  • Constipation
  • Joint pain
  • Fatigue
  • Hair loss

What Happens During a Thyroid Antibodies Test?

A health care professional will take a blood test from a vein in your arm using a tiny needle. Later the needle is inserted; a limited quantity of blood will be collected into a test tube or vial. You might feel a slight sting when the needle goes in or out. It usually takes under five minutes.

There is minimal risk involved in having a blood test. One may experience slight pain at the spot where the needle was inserted, but it usually goes away quickly.

What Do the Results of the Test Shows?

(i) Negative: It means no thyroid antibodies were found and the thyroid symptoms are probably not because of an autoimmune disease.

(ii) Positive: It means antibodies to TPO and/or Tg were found. This shows you may have Hashimoto disease as people with Hashimoto disease usually have high levels of one or both of these types of antibodies.

(iii) Positive: It means antibodies to TPO and TSH receptors were found, and you may have Grave's disease.

Thyroid disease usually gets worse during pregnancy and can also harm the mother and unborn baby. It is thus suggested to book pathology tests online to determine the cause if you are experiencing any thyroid symptoms. Never ignore testing, as blood tests are the most accurate way to diagnose and manage thyroid disorders. In case you require further information about thyroid disorder, visit Trulabs today.
