Toxic & Essential Elements Urine home test kit is used to evaluate if an individual has too little, or too much, of the essential nutrients iodine and selenium or the trace elements bromine and lithium.  Also, if the individual has been exposed to too much of the toxic elements, arsenic, mercury, and cadmium.


Test Code:






Refrain from drinking more than 8 oz water in the hour before each dried urine strip collection to allow your urine to concentrate. Specimen must be sent to lab by overnight mail Monday-Thursday only. Please read patient instructions very carefully and decide the ideal day for you to begin test.

Test Results:

5-7 Days once the lab receives the specimen. May take longer based on weather, holiday or lab delays.

Iodine is an essential component of T3 and T4, so its deficiency has a serious impact on thyroid hormone synthesis, while selenium is a component of the selenoproteins, including the deiodinases that convert inactive T4 to active T3, and glutathione peroxidase, an important antioxidant. Arsenic and mercury reduce selenium’s bioavailability and disrupt thyroid health. Arsenic, mercury, and cadmium represent 3 of the 4 most toxic heavy metals according to the CDC. Lithium is important for brain health in trace amounts but is toxic when used in excessive amounts pharmacologically.

This test kit should be considered for Smokers, patients at risk of exposure to toxic heavy metals, or patients with thyroid issues and/or possible disruption of T4 to T3 conversion due to excesses or deficiencies of the elements tested.

The Toxic & Essential Elements Urine test kit includes Iodine, Selenium, Bromine, Lithium, Arsenic, Cadmium, Mercury, and Creatinine.
