Iodine Test Kit

Dried urine is for testing elements (iodine, selenium, bromine, arsenic and mercury) that directly or indirectly impact thyroid hormone synthesis and intracellular conversion of T4 to T3. Dried urine tests have also been developed for measuring steroid hormones and their metabolites. Urine dried on filter paper produces results nearly identical to liquid urine, but has clear advantages in sample transport, size and stability compared to typical 24-hour urine collections.
