Urine Iodine (24 hr or Random/FMV)
Doctor's Data
Sample type: Urine
Requires fasting: No
At home test
Details
Iodine is an essential element required for normal function of the thyroid gland and immune system, and the integrity of breast tissue. The test is performed using conventional random or 24-hour urine collection. Iodine is measured by ICP-MS, as is used by the CDC.
- Iodine
Estimated days for results: Results should arrive 5 to 7 days after the lab receives samples.
Specific tissues in the body require adequate iodine and the reduced form of the element, iodide, for normal metabolism and optimal health. Adequate iodide uptake and organification of iodine by the thyroid gland is required for the production, storage and release of thyroid hormones.
Triiodothyronine (T3) regulates metabolism in several tissues by affecting energy production and neuronal and sexual development. Iodine insufficiency is associated with "sub-clinical" thyroid deficiency, weight gain, loss of energy, goiter and impaired mental function. Iodine is also concentrated in breast tissue where it elicits anti-proliferative effects and protection against fibrocystic breast disease and cancer. Iodine and organic iodine compounds are also concentrated and secreted by the gastric mucosa, salivary glands and the cervix.
The test requires a spot urine specimen, preferably first morning void (FMV) or all urine is collected for 24 hours. Iodine is measured in the urine and the results for each element are reported as µg/gm creatinine and µg/24 hours. Iodine status is assessed by evaluation of the percentage of the ingested dose that is excreted. Low iodine excretion is suggestive of greater bodily retention and need. Iodine is measured by ICP-MS, as is used by the CDC.

Before You Start: Please read all of the directions, and familiarize yourself with the collection procedures.
The Urine Halides/Iodine pre & post loading test takes 24 hours to collect. The urine container holds a maximum of 4 liters. For best results, do not consume more than 3.5 liters (15 cups) of liquid during the collection period to avoid overfilling the container. For 5 days prior to and during the collection process you should avoid taking iodine supplements (other than the loading dose prescribed by your physician), non-essential medications and products that contain iodide/ iodine such as kelp, fish, and sea vegetables unless otherwise instructed by your physician. Never discontinue prescription medications without first consulting your physician. Female patients should not collect urine during a menstrual period. Use the provided vial and collection containers to avoid contamination of the specimen. Use of other collection materials may result in falsely elevated results.
