The Urine Iodine Pre & Post Load Test Kit comprehensively assesses iodine sufficiency in a urine sample collected over 24 hours.


Test Code:







This test takes 24 hours to collect. The urine container holds a maximum of 4 liters. For best results, the patient should not consume more than 3.5 liters (15 cups) of liquid during the collection period to avoid overfilling the container. For five days before and during the collection process, the patient should avoid taking iodine supplements (other than the loading dose prescribed by their physician), non-essential medications, and products containing iodide/ iodine, such as kelp, fish, and sea vegetables, unless otherwise instructed by their physician. Patients should consult with their physician before discontinuing prescription medications. Female patients should not collect urine during a menstrual period.

Test Results:

5-7 business days once the lab receives the specimen. May take longer based on weather, holiday or lab delays.

Please Note: This test kit requires a dosage of iodine. The iodine is not included in this kit, and we cannot advise the amount you should take. We can only guarantee accurate results if the correct dosage is taken. Patients are advised to contact their physician for dosage information.


What is the purpose of this test?

Order this Urine Halides Pre & Post Load Test Kit, which comprehensively assesses iodine sufficiency in a urine sample collected over 24 hours. Iodine is an essential element required for the normal function of the thyroid gland and immune system and the integrity of breast tissue. The body doesn’t produce its iodine. Instead, it must obtain iodine through the food we eat, such as:


  • Seaweed
  • Shrimp and other seafood
  • Certain dairy products and other foods fortified with iodine
  • Table salt
  • Daily multivitamin


Iodine insufficiency occurs when an individual doesn’t get enough iodine in their diet. While rare in the United States, iodine insufficiency is common in developing countries worldwide. For example, individuals in areas at higher altitudes or far from water don’t get enough iodine through seafood or dairy. In addition, iodine isn’t added to table salt in some areas of the world. Pregnant women also risk developing an iodine insufficiency because they require 50% more iodine than non-pregnant women to get enough iodine for their unborn babies.


This test kit is helpful for individuals experiencing issues with the following:


  • Fatigue
  • Immune Response
  • Thyroid Function
  • Estrogen Metabolism
