Advanced Thyroid blood test
The thyroid gland is the gland that is responsible for creating the hormones that regulate the metabolic function of the body. When the thyroid gland does not produce the hormones in the right way or if the hormones produced are not as effective as they need to be, you may notice that you are suffering with one or more symptoms.
Autoimmune disorders such as Graves disease or Hashimoto’s disease can cause thyroid problems such as hyperthyroidism (Graves disease) or hypothyroidism (Hashimoto’s disease).
Our Advanced Thyroid Blood Test will test for thyroid disease (hyper and hypo thyroid) as well and the antibodies associated with Graves or Hashimoto’s disease
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 from a finger prick which you can do yourself.
The main treatment for hypothyroidism/underactive thyroid is medication.
How often do I need to check my thyroid levels
We recommend checking your thyroid levels when you experience any health changes or symptoms listed.
- Dry skin
- Increased sensitivity to the cold
- Slow heart rate
- Weight gain
- Memory issues
This blood test is to check on:
- Thyroid function
- Thyroid antibodies
For best results (if medically suitable) it is advisable to fast (water is allowed) 12 hours prior to the test which needs to be taken first thing in the morning and posted on the same day on a Monday, Tuesday or Wednesday.
Collection method: Finger prick
Results available: 2-5 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.
The test will measure the amount of thyroxine in your blood. Too much or too little may be indicative of 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.
