I am thinking about ordering a urinary iodine test, now what?

What test to order?

  • Spot: This test is a basic check to examine if you are ingesting enough iodine to prevent goiter.  The results are compared to World Health Organization recommendations.
  • 24 hour load test/challenge: This test examines total body sufficiency for iodine.  Iodine is important for every tissue and organ in the body, not just the thyroid.  After ingesting a 50mg load dose, every urine excretion is collected for a 24 hour period. 
  • Combination (spot and load): Both of the tests (spot and load) completed at the same time.

Should I add bromide, fluoride, and/or chloride?

  • These three, along with iodine are in the halogen family of the periodic table.  Where iodine is useful in every tissue and organ, bromide and fluoride have no use in the body.  They compete for binding sites within the cell. 
  • A decision to add these elements does not have to be made with the initial order.  Samples are held and kept stable in the lab for 30 days.  Call anytime within that 30 day period if you would like us to pull your sample from storage for additional testing.

Are there any foods/beverages/supplements I should avoid before testing?

  • Kelp
  • Seaweed
  • Supplements containing iodine, including multi-vitamins
  • Refrain from ingesting anything containing iodine 3 days (72 hours) before beginning testing.
