thyroid blood test

The Thyroid gland is located just below the Adam’s apple, in front of your neck, and is also a vital part of the endocrine system. It produces two significant hormones: thyroxine (T4) and triiodothyronine (T3), which regulate the metabolism, functioning of tissues, organs and cells, and energy production. The pituitary gland produces the TSH, i.e., Thyroid stimulating hormone, which regulates these hormones.   

What is crucial for you to know is about thyroid disorders and thyroid tests of different kinds used to diagnose the issue. So, if you are experiencing an unusual weight imbalance, fatigue, changing heart rate, anxiety, etc., that you cannot point anything to, then do not neglect and find out the nitty-gritty of a thyroid scan. 

The first step to cure is ‘awareness’: Thyroid disorders and their symptoms.

The classification of thyroid disorder is of two kinds-

  1. Hypothyroidism –

A lack of thyroid hormones causes this disorder because of iodine deficiency, autoimmune diseases, etc. Symptoms of hypothyroidism include –

  • Weight gain
  • Fatigue
  • Sensitivity to cold temperature
  • Irregularity in menstrual flow
  • Hair loss
  • Constipation
  • Dry skin
  • Depression

2. Hyperthyroidism- 

This disorder arises due to an excessive production of thyroid hormones in the human body. Another cause might be an autoimmune illness. Symptoms of hyperthyroidism may include-

  • Weight loss
  • Rapid heartbeat
  • Tremors, shaking, shivering
  • Diarrhea
  • Irritability
  • Puffiness caused due to lack of ability to sleep
  • Bulging of eyes
  • Anxiety

Before the diagnosis, your doctor must glance through your thyroid test conducted by expert technicians, like in Aglius diagnostic. So, if you realize the occurrence of any one or more symptoms from the list above, then approach a healthcare provider now to get your quick thyroid scan done. 

The different kinds of thyroid test

A thyroid test is usually a blood test taken to evaluate the cross-examination of the functionality of a thyroid gland. The three significant kinds of blood tests are below-

  • TSH test- As mentioned earlier, TSH is a Thyroid stimulating hormone secreted by the pituitary gland, which also controls the production of triiodothyronine (T3) and thyroxine (T4) in your body. If you are having symptoms of hyperthyroidism, then it might be because of low levels of TSH that the TSH test will reveal, and your high level of TSH might indicate an issue of hypothyroidism. 
  • T3 test and T4 test- T3 and T4 are free-flowing hormones in the blood, as indicated above. Doctors usually prescribe both tests to be taken simultaneously to understand any difference in the disbalance of hormones and correctly identify thyroid dysfunction. Suppose you have a high concentration of T3 and T4 in your body. In that case, you might already be experiencing symptoms of hyperthyroidism, and the contrast result of a T3 test or even a T4 test will indicate otherwise.

Besides these blood tests, there are other ways to thyroid scan as well-

  • Ultrasound- This test minutely examines the presence of thyroid nodules using mechanical waves, which gather an image of your throat. This thyroid test is crucial for you if you are suffering from adverse symptoms, as thyroid nodules might also be cancerous. So usually, doctors prescribe this thyroid scan by a radiologist when the situation is serious.
  • Thyroid scan- A scan taken using radioactive iodine to detect the presence of thyroid nodules in your thyroid gland. It also explains the shape, size, structure, and other potential abnormalities. 

Preparing yourself for the ‘pre’ and ‘post’ of the thyroid scan

Before the thyroid test-

In the standard set of events, a doctor won’t ask you to observe a fast before a TSH test or any other blood thyroid scan. However, it is better to cross-check with the doctor to understand the subjectivity of your case. Vitamin B7 is suggested to be avoided before a thyroid test like the T3 test, and it is better not to take Thyroid medicines, as they would influence your test results for the T4 test. For the ultrasound test and the thyroid scan, doctors suggest avoiding food with high iodine content for one week preceding the test.

After the thyroid scan-

A thyroid blood test usually has no risks or side effects. So, one can return to one’s usual routine; however, if you experience any bruise or bleeding from the area where the blood was collected, it is advisable to apply ice packs.

The Thyroid is a severe disorder that people often neglect, which becomes the cause of potential health hazards in the future. In women, it may even impact their fertility, pregnancies, health condition of babies, etc. Therefore, it is essential to identify the presence of any abnormality in thyroid hormone as early as possible using a thyroid scan. 

As soon as you notice any symptom of hyperthyroidism or hypothyroidism, get that TSH test done or whatever your health care provider advises you to take. And in this chaos of enduring weak health and scrutinizing its presence using a thyroid test, place your trust in the safe hands of Aglius Diagnostics
