Iodine Assessment
Doctor's Data, Inc. offers three urine iodine report formats and collection options to allow the practitioner a wide range of assessment options to fit an individual patient's needs.*
  • Traditionally, the level of urinary iodine from a twenty-four hour collection has been utilized to assess iodine intake as compared to the general population.

  • In situations where patient compliance is
    difficult, a spot urine collection, preferably the first
    morning void provides indication of iodine intake when expressed per mg creatinine.

  • In more recent times, an iodine load test has become a useful analysis for practitioners. A specified oral dose of iodine (ex. Lugol’s) is given and urine is collected for the subsequent twenty- four hours. This test is based on the concept that the body has specific and saturable mechanisms to take up iodine. When maximal retention is attained, the percentage of an iodine/iodide load that is retained decreases and the percentage urinary excretion increases.



 * Doctor’s Data utilizes the CDC-recommended ICP-MS analysis of iodine.
Halide Assessment   
Iodine status and metabolism is affected not only by iodine
intake, but also by intake and retention of goitrogenic
halides (bromide and fluoride). Iodide uptake by specific cells is mediated by an energy-dependent sodium/iodide
symporter (NIS). Bromide and fluoride are non-essential, toxic halides that avidly compete with iodide for the NIS. 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.

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. The test can be performed using conventional random or 24-hour urine collection or after administration of a loading dose of iodide/iodine.
