Urine Thyroid Hormones (T3/T4) + Iodine



There is no one perfect way, no one symptom nor test result, that will properly diagnose low thyroid function or hypothyroidism. The key is to look at the whole picture – your symptoms and your blood tests – and then decide.

To get a complete picture, a 24-hour urine test for free T3 can be helpful in hard-to-diagnose cases

This test is a cost effective method of combining the urine thyroid hormone test (T3 & T4 only) with urinary iodine. Iodine is vital for optimal thyroid health and deficiencies are often implicated in hypothyroidism.
