Thyroglobulin (Tgbn) Test Kit is designed to test for Thyroglobulin (Tgbn), and it accurately assesses Tgbn levels in the body. The Thyroglobulin Test allows you to accurately check your levels of Thyroglobulin Antibodies in a fingerprick blood sample.
Thyroglobulin is a protein synthesised only in the thyroid gland. It is rich in the amino acid tyrosine, which forms conjugates with the iodine that is actively transported into the thyroid gland via the sodium-iodide symporter. The iodine-enriched thyroglobulin, the source material for synthesising the thyroid hormones T3 and T4, is stored in the lumen of the thyroid gland. When activated by thyroid-stimulating hormone (TSH), the iodinated thyroglobulin is translocated into the thyroid follicular cells, where it is hydrolyzed to release T4 and T3 into the bloodstream.
When there is insufficient iodine intake for normal thyroid hormone synthesis, thyroglobulin is poorly iodinated and leaks into the bloodstream, raising blood levels above normal. While very elevated blood levels of thyroglobulin are used as a marker for thyroid cancer, moderately elevated levels are a good indicator of an individual’s average exposure to iodine over a period of weeks. Urinary iodine can fluctuate depending on variations in daily consumption of iodine-containing foods; therefore, blood spot thyroglobulin is a better indicator of longer-term iodine status. Thyroglobulin levels are also raised in autoimmune thyroiditis (Hashimoto’s disease) as the destruction of thyroid tissue releases thyroglobulin into circulation. The reference range for thyroglobulin is 3—40 ng/mL (optimum 3—10 ng/mL).
We strongly recommend that you consult your results with your health care provider, GP, or doctor to know whether or not any further actions need to be carried out and get started with ample treatment if needed.

How does the test carry out?
This blood spot-based testing tool can be done in the privacy of your home. A simple step of collecting your blood spot for the test is required. Once you provide a blood spot, you need to seal the sample and send it off to us. Your test result report will be emailed to you between 3 and 5 working days after the laboratory receives your sample.
