How much does it cost?

Please note – In addition to the price of tests, there is also a phlebotomy cost for the withdrawal and handling of your sample. This is a standard charge across all clinics. The cost of sample handling is £50, but this is discounted to £30 only if paid in advance. Please choose the pay later option to pay the full amount upon your arrival at the clinic or choose pay now in order to pay in advance and secure the discounted fee.

What can I learn from this test?

This test helps you understand whether any symptoms you are experiencing could be caused by an overactive or underactive thyroid. It includes 3 important thyroid-related hormones to help explain any symptoms you may have. These include free thyroxine (FT4) and the more biologically active free triiodothyronine (FT3) as well as thyroid stimulating hormone (TSH). The majority of thyroid disorders are caused by autoimmune conditions where your body’s immune system attacks the thyroid gland. This test measures your thyroid antibodies (thyroglobulin and thyroid peroxidase antibodies) to help you learn whether an autoimmune condition could be affecting your thyroid function.

What can I test?

Free T3

Triiodothyronine (T3) is the more active of the two thyroid hormones produced by the thyroid gland. Most T3 is bound to protein in the blood. Free T3 measures the level of T3 that is free, or unbound to protein, and is available to regulate metabolism.

Free T4

Thyroxine (T4) is one of two hormones produced by the thyroid gland. It works to speed up the rate of your metabolism. Most T4 is bound to carrier proteins in the blood - it is only the free, or unbound, T4 that is active in the body, which is measured in this test. Free T4 is the less active of the two main thyroid hormones. To have an impact on your cells it needs to convert to the more active T3 when your body needs it.

Thyroid stimulating hormone (TSH)

Thyroid stimulating hormone (TSH) is produced in the pituitary gland in order to regulate the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. If thyroid hormones in the blood are low, then more TSH is produced to stimulate the thyroid gland to produce more of them. If thyroid hormone levels are high, then the pituitary produces less TSH to slow the production of thyroid hormones. If TSH is too high or too low, it normally signifies that there is a problem with the thyroid gland which is causing it to under or over produce thyroid hormones. Sometimes a disorder of the pituitary gland can also cause abnormal TSH levels.

Thyroglobulin antibodies (TgAb)

This test looks for antibodies to thyroglobulin, a protein which is specific to the thyroid gland. Under normal circumstances it does not enter the bloodstream, but if your thyroid is inflamed or under attack from the body's own immune system, then thyroglobulin can be secreted and antibodies detected. Most cases of thyroid disease are caused by an autoimmune condition where the thyroid gland is attacked by the body's own immune system. This can cause the thyroid gland to produce more thyroid hormone (as in the case of Graves' disease) or to produce less as the cells in the thyroid gland are gradually destroyed (as in the case of Hashimoto's thyroiditis).

Thyroid peroxidase (TPO)

Thyroid peroxidase (TPO) is an enzyme important in the production of thyroid hormones. This test looks for antibodies against TPO which are often raised in cases of autoimmune thyroid conditions and occasionally in healthy individuals.

Free T3

Triiodothyronine (T3) is the more active of the two thyroid hormones produced by the thyroid gland. Most T3 is bound to protein in the blood. Free T3 measures the level of T3 that is free, or unbound to protein, and is available to regulate metabolism.

Free T4

Thyroxine (T4) is one of two hormones produced by the thyroid gland. It works to speed up the rate of your metabolism. Most T4 is bound to carrier proteins in the blood - it is only the free, or unbound, T4 that is active in the body, which is measured in this test. Free T4 is the less active of the two main thyroid hormones. To have an impact on your cells it needs to convert to the more active T3 when your body needs it.

If thyroid hormones in the blood are low, then more TSH is produced to stimulate the thyroid gland to produce more of them. If thyroid hormone levels are high, then the pituitary produces less TSH to slow the production of thyroid hormones. If TSH is too high or too low, it normally signifies that there is a problem with the thyroid gland which is causing it to under or over produce thyroid hormones.
