What is a Thyroid Test?

A Thyroid Test is a blood test which plays an important role in determining the hormone levels produced by the thyroid gland. This helps in the regulation of growth & development and metabolism. Thyroid Tests are significant in measuring the levels of T3, T4 and TSH hormones. Signals towards thyroid disorders can be detected under abnormal hormone levels such as hyperthyroidism (overproduction of hormones) or hypothyroidism (underproduction of hormones.

TSH, also known as Thyroid-Stimulating Hormone or Thyrotrophic, is a hormone produced by the pituitary gland, a small gland located at the base of the brain. It plays a key role in regulating the thyroid gland’s function.

Functions-

  • Helps in diagnosing thyroid disorders.
  • Performs a key role in maintaining thyroid hormone levels.
  • Stimulating thyroid hormone production.

A low TSH level shows hyperthyroidism or the overactive thyroid whereas a high TSH level signifies hypothyroidism or the underactive thyroid,

Also known as: Thyrotropic Hormone, Thyrotropin Test.

T3 and T4 are two primary hormones released by the thyroid gland, which is a butterfly- shaped structure located at the front of the neck. These hormones play an essential role in regulating various bodily functions, including growth and development and metabolism.

T3 (Triiodothyronine)

T3, a stronger active type of thyroid hormone, which directly influences the body’s tissues and cells to raise their metabolic rate. T3 thyroid test comprises of two tests, a Free T3 test and a Total T3 test.

Functions-

  • This regulates body temperature by increasing heat production.
  • Regulating metabolism, where the body utilizes energy from food.
  • Functional impact and brain development, especially in children and infants. It also implies contribution to cognitive abilities in adults.

Also known as: Thyroid Function Test, Total Triiodothyroxine, Free Triiodothyroxine, FT3, TT3, Radioimmunoassay FT3.

T4 (Thyroxine)

T4, a primary storage form of thyroid hormone formed by the thyroid gland, works as a reservoir for T3.

The level of T4 thyroid hormone is measured with either a total T4 test or a free T4 test.

Functions-

  • The majority of biologically active T4 are converted into T3.
  • Regulation in metabolism, though its effects are not as strong as T3.
  • Support in growth and development, particularly in Children.

What is the relationship between T3 and T4?

It is essential that a proper balance is struck between T3 and T4 for thyroid to function optimally. Production of T3 and T4 is managed by the Thyroid-Stimulating Hormone (TSH), which is formed by the pituitary gland.

When to get thyroid function testing done and what are the indications?

Doctor or physician may prescribe Thyroid test under the following conditions

  • Age-specific guidelines, Adults between 35 years to 65+ years old, from baseline testing to testing in every 1-2 years and for newborns screening for Congenital Hypothyroidism
  • Under medical conditions like, High Cholesterol, Diabetes, Osteoporosis, Hypertension (blood pressure), Heart Diseases, Autoimmune Disorders (e.g., Lupus, Rheumatoid Arthritis).
  • Under particular circumstances like, Infertility, Recurrent Pregnancy Loss, Miscarriage, Radioactive Iodine Treatment, Cancer Treatment (Radiation Exposure), Postpartum Thyroiditis.
  • Other symptoms can be Goiter, hypersensitivity to heat and cold, sweating, Palpitations, Irregular heartbeats, Nervousness and Irritability.
  • Hormone imbalance or body function not normal due to over or under production of thyroid

If such indications are evident, it is suggested to consult the patient’s health provider for diagnosing and proper treatment and medications.

What does Thyroid Test show?

A thyroid test is generally done by blood test that helps us to detect diseases that arises due to under or overflow of thyroid hormone. Diseases like Hashimoto (most common hypothyroidism) and Grave disease (most common hyperthyroidism). Thyroid test helps us checking the levels of TSH, under which T3 and T4 produces hormones. Thyroid levels are measure in (Mu/l), high level of TSH indicates that the person has Hypothyroidism which low level of TSH indicates Hyperthyroidism in a person.

What do Thyroid Test results mean?

Thyroid test measures the level of TSH, a high or low level does further indicate diseases like hyperthyroidism and hypothyroidism.
