We will post out to you a finger prick sample pack; it will have all you need to take your sample including instructions of how to take the sample and an envelope to return it to the Lab.
If you are nervous or unsure about anything please contact us and we will do our best to help.
We always recommend taking your sample in the morning and getting to the post office the same day.
Your kit will have a self-addressed envelope enclosed to return the sample by 1st class post, if you are unsure of the level of service in your area you may wish to upgrade to a guaranteed next day service.
Your blood sample will be analysed at the accredited doctor’s laboratory in London. They are very professional and quick to upload the data; your results should be ready the same day they are tested.
Once your results are uploaded on your bespoke platform we will let you know our thoughts on the results of your test and offer information about having a consultation with the doctor if necessary.
Thyroxine (T4) is one of two hormones produced by the thyroid gland. Most T4 is bound to carrier proteins in the blood – this test measures the level of T4 which is free, or unbound, circulating in your blood.
High levels of free thyroxine can indicate an overactive thyroid while low levels can indicate an underactive thyroid.
Thyroid Stimulating Hormone is produced in the pituitary gland and stimulates the thyroid gland to produce thyroid hormones thyroxine (T4) and triiodothyronine (T3).
High levels of TSH indicate an underactive thyroid while low levels indicate an overactive thyroid. In primary pituitary failure, a low TSH will be associated with an underactive thyroid.
Triiodothyronine (T3) is one of two thyroid hormones produced by the thyroid gland. Most T3 is bound to protein in the blood. It helps to regulate metabolism. Free T3 measures the level of T3 that is free, or unbound to protein.
