Iodine 24hr Urine Test (Labcorp)
This test measures the level of Iodine in a person's urine. Iodine is an element which is essential for healthy functioning in many organs and systems such as the thyroid, heart, liver, lungs, and immune system. Iodine aids in the production of thyroid hormones which are vital for good health. A 24 hour urine test measures the amount of iodine excreted from the body. Urinary Iodine levels can help determine if a person is getting healthy amounts of iodine from the food they eat. Unusually high or low levels of iodine can lead to a number of disorders such as hyperthyroidism or hypothyroidism.
Because levels of substances like iodine can fluctuate throughout the day, evaluating a urine collection over 24 hours can provide a more accurate evaluation than a urine test which only looks at a single collection.
This test is usually ordered when someone has had irregular results from thyroid tests such as TSH, T3 and T4. Pregnant and nursing women are often tested for iodine because deficiency can have adverse effects on pregnancy and cause developmental difficulties in infants.
Customers looking for additional thyroid testing may wish to order our Thyroid Basic Panel with TSH.
Turnaround time for the 24 Hour Urine Iodine test is typically 1-3 business days.

Requirements:
For 24-hour urine specimen: Obtain a specimen container and instructions from the draw site. Void at 8 AM and discard the specimen. Then collect all urine including the final void at the end of the 24-hour collection period (ie, 8 AM the next morning) in the specimen container. Screw the lid on securely and return the container promptly to the draw site.
If this test is being ordered along with any other blood and/or urine medical testing, it is recommended you have the specimen(s) for your other tests collected at the same time you bring the 24-hour urine specimen to the draw site.
