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.
- T3 (urine)
