Urine Thyroid Hormones (T3/T4)

The elevation of thyroid hormone levels in urine, assesses tissue exposure to thyroid hormones over a 24-hour period. The urine thyroid test therefore serves as a valuable tool for detecting those patients that are suffering from thyroid dysfunction, particularly low grade hypothyroidism who might otherwise go undetected through standard blood tests. It is important to use this test as an adjunct to other indicators of thyroid function, such as body temperature, symptomology and standard blood thyroid tests.
