What's included in the test?

Autoimmunity

Thyroglobulin Antibodies
This test detects antibodies against thyroglobulin, a protein specific to the thyroid gland. Normally, thyroglobulin does not enter the bloodstream, but if the thyroid is inflamed or under immune system attack, it may be released, allowing antibodies to be detected. Most thyroid disorders result from autoimmune conditions, where the immune system mistakenly targets the thyroid. This can lead to excessive thyroid hormone production, as seen in Graves' disease, or reduced hormone levels due to gradual destruction of thyroid cells, as in Hashimoto's thyroiditis.

Thyroid Peroxidase (TPO) Antibodies
Thyroid peroxidase (TPO) is an enzyme essential for producing thyroid hormones. This test checks for TPO antibodies, which are frequently elevated in autoimmune thyroid conditions and sometimes present in individuals without symptoms.

Thyroid Hormones

TSH (Thyroid Stimulating Hormone)
TSH is produced by the pituitary gland to regulate thyroid hormone levels. When thyroid hormone levels in the blood are low, TSH increases to stimulate hormone production. Conversely, if thyroid hormone levels are too high, TSH production decreases to slow down hormone synthesis. Abnormal TSH levels often indicate an issue with the thyroid gland, such as over- or underproduction of hormones, though pituitary disorders can also affect TSH levels.

Free T3 (Triiodothyronine)
T3 is the more active thyroid hormone responsible for regulating metabolism. Most T3 in the blood is bound to proteins, but this test measures the free (unbound) T3 that is available for use by the body.

Free T4 (Thyroxine)
T4 is one of the main thyroid hormones that influences metabolism. Most T4 is bound to carrier proteins, but only the free (unbound) T4 is biologically active, which is what this test measures. Free T4 is less active than T3 and must convert into T3 when required by the body.

How to prepare for your test

Follow these guidelines to ensure accurate results:
