Screening Thyroid Hormone Levels
The thyroid gland is a small organ shaped like a butterfly and located at the neck base. It is part of the endocrine system, which coordinates various bodily functions. The thyroid gland plays a vital role in regulating your development, metabolism, and growth by producing crucial hormones such as T3 and T4.
Screening thyroid hormone levels is a simple test designed to assess essential hormone levels made by the thyroid gland. These include thyroid-stimulating Hormone (TSH), thyroxine (T4), and triiodothyronine (T3).
TSH, produced by the pituitary gland, controls the production of T3 and T4. When the thyroid produces too much or too little of these hormones, it can lead to symptoms such as weight changes, fatigue, irritability, and other health concerns. Maintaining balanced hormone levels is essential for overall health.
Any imbalance in these hormones can significantly impact your health and well-being. Interestingly, thyroid disorders are far more prevalent in women, occurring up to 15 times more frequently than in men.
Our thyroid function test measures key hormone levels, including Triiodothyronine (T3), Thyroxine (T4), and Thyroid-Stimulating Hormone (TSH), to assess your thyroid’s health. This comprehensive screening can help pinpoint the cause of fatigue and other related symptoms.
Why should you opt for a thyroid function test?
This test is crucial because hormone imbalances can result in conditions such as hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid). It can also identify underlying thyroid conditions like thyroid cancer, Hashimoto’s thyroiditis, and Graves’ disease. Proper thyroid function is particularly important for pregnant mothers as it affects foetal development.
A thyroid function test measures the levels of TSH, T3, and T4 in your blood to determine if your thyroid is functioning as it should.
Who needs to undergo this test?
Consider a thyroid function test if you:
- Are over 60 years of age.
- Have undergone radiation treatment to the head, neck, or chest.
- Have a family history of thyroid disorders (e.g., Hashimoto’s thyroiditis, Graves’ disease, or thyroid cancer).
- Are experiencing a goitre (enlarged thyroid gland).
- Are on medications such as lithium or amiodarone.
- Are pregnant or planning to conceive
