Testing a Free-T4, a Free-T3, a TSH and a Thyroid peroxidase antibody allows us to measure the state of the thyroid.
If the pituitary gland detects a drop in the level of thyroid hormones in the blood it increases the production of Thyroid Stimulating Hormone (TSH). In a normal person, this causes the thyroid gland to produce more T4 which is converted to the active hormone; T3.
If the thyroid gland is under active (Hypothyroidism) this increase in TSH will have little so the Free T4 and Free T3 will remain low and the TSH will climb higher. Conversely, if the thyroid gland is overactive (Hyperthyroidism) then the Pituitary will stop producing TSH and the Free-T4 and Free-T3 will be high. One of the common reasons the thyroid gland fails is due to the body attacking it with antibodies, the most common antibody is anti-Thyroidperoxidase.
We can test for a range of different allergies and health markers, using one of our home-testing kits. In this kit, you'll be able to test:
General indicators of potential thyroid issues
Additional measures to give a more accurate picture of a person's thyroid.
Once you've got your kit, make sure to read all of the enclosed instructions - they'll make sure you easily and safely get the best sample possible.
Time to take your sample. All of our health tests come with the exact tools you need to take a sample in the comfort of your own home.
