List of thyroid function tests

Check it out. Is thyroid abnormal? Thyroid patients may experience thinning or obesity, swelling, goiter or bulging eyes, which can occur. If there is an abnormal thyroid function, both hyperthyroid (thyroid gland produces too many hormones) and hypothyroid (thyroid gland is under-functioning) will have different symptoms.

Thyroid examination details

There are 5 thyroid function tests listed as follows:

  1. Thyroid Stimulating Hormone (TSH)
  2. Triiodotyronine levels (Free T3)
  3. Tyroxine level check (Free T4)
  4. Triiodothyronine (T3) levels were detected.
  5. Thyroxine (T4) levels
Nowadays, many people suffer from thyroid disease without realizing it. Because I don’t know this disease well enough.

  • Measure thyroid hormone content The amount of thyroid hormones T3 and T4 in the blood whether it is malfunctioning or not. If it is not normal, it translates into the presence of symptoms of thyroid disease.
  • Thyroid-Stimulating Hormone (TSH) is a measure of the amount of pituitary hormone, which is responsible for regulating thyroid function.
  • Thyroid antibody content measurement
In case of risk and need to be examined more accurately to plan treatment, there will be additional X-rays and ultrasounds, which will allow the doctor to see the functioning and abnormalities of thyroid hormones more clearly.

General information about thyroid examinations

The thyroid gland is an endocrine gland located in front of the larynx, responsible for producing and secreting thyroid hormones into the bloodstream to send them to various organs to help the body function normally. Under the control of the pituitary gland, thyroid hormone is important for stimulating the functioning of organs throughout the body, especially the heart and brain, as well as regulating cellular metabolism. Blood lipid levels, digestive system, body temperature If the thyroid gland is abnormal, it affects various systems . Screening assesses the functioning and potential abnormalities of the thyroid gland by taking a blood test to see the levels of thyroid hormones, which consist of 3 hormones that control each other to keep hormones at normal levels, namely:

  1. Thyroid Stimulating Hormone (TSH)
  2. Triiodothyronine (Free T3) hormone
  3. Thyroxine (Thyroxine: Free T4)

In addition, screening, if thyroid ultrasound is included, it will help to analyze thyroid abnormalities more clearly. Diseases caused by thyroid dysfunction Thyroid diseases are more common in women than men.

  • Hyperthyroidism is a condition in which the thyroid gland is overworked. This causes thyroid hormone poisoning. The body burns abnormally much, causing a sharp weight loss. Abnormally fast heartbeat, palpitations, easy sweating, easy heat, and tantrums.

This causes pain when palpating at the lump. Chronic type section It is caused by impairment of the immune system. Usually have a big neck, but you don’t feel any pain.

  • Thyroid cancer is both mild and curable and very severe that can cause death within a short period of time.


  • Generally, thyroid hormone tests may examine all three hormones simultaneously or only preliminary TSH first, at the discretion of the physician and the patient’s condition.
  • Thyroid hormone testing should be checked when there are symptoms of hyperhyrosis or low thyroid hormones. From certain conditions that cause the functioning of the thyroid gland to change.
  • There is no evidence to support that thyroid screening in people with no abnormal symptoms or risk will.
  • It’s more useful than not checking.
