Advanced Thyroid Blood Test
A blood test that checks your levels of all thyroid hormones
What is this test?
The thyroid gland in the neck produces hormones that regulate various bodily functions, including metabolism, energy levels, and growth. An advanced thyroid blood test assesses all major hormones linked to thyroid function.
Advanced thyroid blood tests are commonly recommended to diagnose and monitor conditions such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). It is also used to diagnose disorders such as thyroiditis or if you have been diagnosed with an autoimmune disease such as rheumatoid arthritis or lupus.

Understanding Thyroid Function
If you are experiencing symptoms associated with thyroid disorders, such as unexplained weight changes, fatigue, changes in mood or energy levels, hair loss, menstrual irregularities, or other related symptoms, a thyroid blood test can help determine if thyroid dysfunction is the underlying cause.
Thyroid blood tests may be a part of routine check-ups, especially for individuals at higher risk of thyroid disorders, such as women over the age of 60, individuals with a family history of thyroid disease, or those with certain autoimmune conditions.
Monitoring Thyroid Medication
For individuals already diagnosed with a thyroid disorder and receiving thyroid hormone replacement therapy, regular thyroid blood tests are essential to monitor the effectiveness of the medication and ensure hormone levels are within the target range.
Fertility and Pregnancy
Thyroid dysfunction can affect fertility and pregnancy outcomes. If you are planning to conceive or are pregnant, your healthcare provider may recommend thyroid blood tests to assess thyroid function and ensure optimal hormone levels for a healthy pregnancy.
Unexplained Weight Changes
Significant and unexplained weight loss or weight gain can be an indicator of thyroid dysfunction. A thyroid blood test can help identify any underlying thyroid-related issues contributing to these changes.
Thyroid hormones play a crucial role in regulating heart function. If you are experiencing symptoms such as a rapid or irregular heartbeat, palpitations, or unexplained changes in blood pressure, a thyroid blood test may be ordered to assess thyroid function and rule out any thyroid-related cardiac issues.
Goitre or Thyroid Nodules
If your doctor detects an enlargement of the thyroid gland (goitre) during a physical examination or if thyroid nodules are discovered, a thyroid blood test may be conducted to evaluate thyroid function and rule out any underlying abnormalities.
