Standard Thyroid Blood Test

Thyroid issues are a relatively common health condition and occur in both men and women, but are more likely to occur in women. Thyroid symptoms are frequently linked with other health conditions, such as menopause, anaemia or a deficiency in Vitamin D.

Why take a Thyroid blood test?

The thyroid is a gland that is responsible for producing the hormones that control metabolism. Sometimes, a thyroid gland that isn’t working as it should can cause certain symptoms. There are two main thyroid disorders that occur when the thyroid gland does not produce the right amounts of hormones, each of which has different symptoms associated with them. They are hyperthyroidism and hypothyroidism.

Hyperthyroidism – or excessive thyroid hormone production – includes symptoms such as:
anxiety, irritability, restlessness, a racing heart, increased sweating, sleep issues, thinning skin, brittle nails and hair, weight loss, muscle weakness and, when Graves disease occurs, bulging eyes.

How to test for hyperthyroidism

Testing for hyperthyroidism can be done with an easy-to-use finger-prick blood test that will measure the thyroid hormones (thyroxine (FT4) and the thyroid stimulating hormone (TSH) in your blood. Results that show a high thyroxine and low TSH levels indicate an overactive thyroid gland.

Treatment for hyperthyroidism, or an overactive thyroid, should be discussed with your GP or healthcare professional and can include medication, surgery or a substantial dose of radioactive iodine.

If the thyroid gland doesn’t produce enough of the thyroid hormones, hypothyroidism – or an underactive thyroid – will occur and has different symptoms.

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 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.
