Providing comprehensive assessment of iodine sufficiency and antagonistic halides in a single test, the Urine Halides test assesses iodine as well as exposure to and retention of bromide and fluoride. Iodine is an essential element required for normal function of the thyroid gland and immune system, and the integrity of breast tissue. Bromide and fluoride are non-essential, antagonistic halides that can disrupt iodine homeostasis and function. The test can be performed using conventional random or 24-hour urine collection or after administration of a loading dose of iodide/iodine.

Nutritional Status

Proper nutritional intake is essential to overall health and provides the raw materials the body needs to function in the form of carbohydrates, proteins, fats, vitamins and minerals. Nutritional testing from Doctor's Data can give you a clear view into nutritional status. Carbohydrates are broken down into sugars and used as energy. Protein is broken down into individual amino acids and used to build and repair muscles, the immune and nervous systems, hormones and organs. The body requires fats which function within the membranes that surround all the body’s cells and are needed to signal hormones. Vitamins and minerals typically function as co-enzymes and have protective anti-inflammatory and antioxidant effects.

The typical Western diet contains too many carbohydrates and saturated fats, and is often low in nutrients such as vitamins and minerals. Poor dietary choices can cause nutritional deficiencies and imbalances which may require dietary changes or nutritional supplementation.

Doctor's Data offers a wide range of nutritional testing profiles used to assess nutritional status and to monitor patient response to nutritional interventions.

Detailed Information

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.

Iodine status and metabolism are affected not only by iodine intake, which has decreased significantly, but also by intake and retention of goitrogenic halides bromide and fluoride. Excessive intake of the antagonistic halides can accumulate in tissues, displace iodine and compromise the production of thyroid hormones and the integrity of the thyroid and mammary glands. Antagonistic bromide is abundant in commercially produced baked goods, soft drinks, pesticides, brominated chemicals and some medications. Primary sources of fluoride include fluoridated water, beverages, toothpaste, mouthwashes and some medications.

The Urine Halides test provides comprehensive assessment of iodine sufficiency and retention of antagonistic halides in a single test. The test requires a spot urine specimen, preferably first morning void (FMV), for determination of baseline halide levels. An oral loading dose of iodine/iodide is ingested and all urine is collected for the subsequent 24 hours. Iodine and displaced bromide and fluoride are 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.

The specific halides are analyzed in urine using the most accurate methodology available for each element. Iodine and bromine are measured by ICP-MS as is used by the CDC. Fluoride is measured by ion selective electrode (ISE). 

Analytes Tested

  • Bromine, urine
  • Fluoride, urine
  • Iodine, urine

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.
