Description
Advanced Thyroid blood test
Your thyroid may be small, but it plays a major role in your overall health. It produces the hormones that regulate your metabolism — influencing how your body uses energy, maintains weight, supports mood, and even controls your heart rate and temperature.
When the thyroid isn’t working properly, it can lead to a wide range of symptoms that are often mistaken for other issues: constant tiredness, unexplained weight gain or loss, low mood or anxiety, feeling too hot or cold, dry skin, thinning hair, or changes in your menstrual cycle.
Our Advanced Thyroid Blood Test goes beyond the basics. It checks your thyroid hormone levels to identify whether you have an underactive thyroid (hypothyroidism) or an overactive thyroid (hyperthyroidism). But it doesn’t stop there — it also tests for thyroid antibodies that may signal autoimmune conditions like Hashimoto’s disease or Graves’ disease, which are among the most common causes of long-term thyroid problems.
Whether you’re experiencing symptoms or just want a clearer picture of your thyroid health, this test provides deeper insight so you can take action.
How to test for hyperthyroidism
To assess whether your thyroid isn’t producing enough of the thyroid hormones, a simple blood test which measures the thyroid hormones (thyroxine (T4)) and the thyroid stimulating hormone (TSH) in your blood. If the results show a high TSH levels and a low thyroxine level could indicate that your thyroid gland is underactive.
The test can be performed using a small amount of blood taken by one of our nurses.
The main treatment for hypothyroidism/underactive thyroid is medication.

Collection method: Venous blood
Results available: 1-2 days after the sample has reached the laboratory.
Free Thyroxine (Free T4)
This test will measure the amount of free thyroxine in your blood, it will measure how well your thyroid gland is working. T4 is one of the major thyroid hormones in your blood. If the results are too high or too low it can indicate thyroid disease.
Thyroid Stimulating Hormone (TSH)
This test will measure how much TSH is in your blood.
TSH is made in your pituitary, (a gland in your brain) when your thyroid levels are low the pituitary gland makes more TSH and when the thyroid levels are high your pituitary makes less TSH This result indicates how well the thyroid is working.
Free T3 (FT3)
This test measures the level of triiodothyronine (T3) in your blood. T3 along with T4 are the two major thyroid hormones in your blood. T3 blood test may be used to diagnose hyperthyroidism. If the results are too high or too low it can indicate thyroid disease.
Thyroid Antibodies (TGA and TPO)
This test measures thyroid antibodies in the blood.
Antibodies are a protein made by the immune system to fight infection and bacteria. Sometimes these antibodies can fight your own cells, tissues and muscles causing an autoimmune response. When this occurs with the thyroid it can lead to an autoimmune thyroid disorder such as Graves disease or Hashimotos disease.
Thyroglobulin Antibodies (TGA)
The thyroglobulin antibodies blood test will usually indicate if an autoimmune problem has caused damage to the thyroid gland.
Thyroid Peroxidase Antibodies (TPO)
The thyroid peroxidase antibodies blood test will usually indicate if an autoimmune problem has caused damage to the thyroid gland.
