This panel measures six thyroid markers — including Free T3, Free T4, and both thyroid antibodies — plus iodine levels via urine. This gives a far more comprehensive view of thyroid health and its nutritional root causes, which a standard test would miss.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is iodine tested through urine and not blood?\u003c\/strong\u003e\u003cbr\u003eUrinary iodine is the internationally recommended method for assessing iodine status. Because the kidneys excrete excess iodine, urine reflects your overall intake and body stores more accurately than a blood sample. We use ICP-MS technology — the most precise measurement method available.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan iodine deficiency cause thyroid problems?\u003c\/strong\u003e\u003cbr\u003eYes. Iodine is a key building block of thyroid hormones T3 and T4. Without sufficient iodine, the thyroid cannot produce adequate hormones, which can lead to hypothyroidism, an enlarged thyroid (goitre), fatigue, and metabolic slowdown. This test identifies whether iodine deficiency may be contributing to your symptoms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are TPO and thyroglobulin antibodies, and why do they matter?\u003c\/strong\u003e\u003cbr\u003eThese are autoimmune markers. Elevated TPO antibodies are the primary indicator of Hashimoto's thyroiditis — the most common cause of an underactive thyroid. Thyroglobulin antibodies (TgAb) are also elevated in autoimmune thyroid disease. Detecting these early allows you to take action before significant thyroid damage occurs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this test suitable for children?\u003c\/strong\u003e\u003cbr\u003eYes. The test is suitable for adults and children. Sample collection is straightforward and non-invasive — the dried blood spot requires only a small finger-prick, and the urine collection is simple. If you are testing a child, please follow the collection instructions carefully.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I collect the samples?\u003c\/strong\u003e\u003cbr\u003eYour kit includes full step-by-step instructions. The dried blood spot is collected via a gentle finger-prick device (lancet). The dried urine sample is collected by applying a small amount of urine to the test card using a pipette. Both samples are then air-dried and posted to the laboratory in the envelope provided.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen will I receive my results?\u003c\/strong\u003e\u003cbr\u003eResults are typically available within \u003cstrong\u003e3–5 working days\u003c\/strong\u003e of the laboratory receiving your samples.

The purchase price includes the full laboratory analysis fee. There are no additional charges. You are only responsible for posting your sample to the laboratory.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long is the kit valid for?\u003c\/strong\u003e\u003cbr\u003eThe kit must be used within \u003cstrong\u003e12 months\u003c\/strong\u003e of the purchase date.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I take this test if I am already on thyroid medication?\u003c\/strong\u003e\u003cbr\u003eYes. This test can be taken while on thyroid medication and is particularly useful for monitoring your levels and understanding whether your current treatment is effective.
