Overview

The Iodine Random Spot Urine Test provides a quick screen of your iodine status from a single morning urine sample. It's the most convenient way to assess whether your iodine intake is adequate, though it reflects recent intake rather than total body stores.

Iodine deficiency has re-emerged as salt intake has decreased and iodine-rich foods have become less common in Western diets. Thyroid function depends on adequate iodine—without it, thyroid hormone production suffers, potentially causing fatigue, weight gain, and cognitive symptoms.

This test suits Australians wanting convenient initial screening for iodine adequacy. Those with persistent thyroid symptoms or borderline results should consider the more definitive loading test.

Symptoms

Essential for convenient iodine status screening, initial assessment of iodine intake, or tracking response to dietary changes.

Questions

  • Spot urine reflects recent iodine intake rather than total body stores. It's useful for screening but has day-to-day variability. First morning urine provides the most consistent results.
  • Results below 100 μg/L suggest inadequate intake. 100-199 μg/L is adequate. 200-299 μg/L more than adequate. Above 300 μg/L may indicate excessive intake.
  • Consider the loading test if spot results are borderline, if you have thyroid symptoms despite normal-appearing spot results, or if you want definitive assessment of total body stores.
  • Recent iodine-rich food, supplements, hydration status, and time of day all affect results. This is why it's a screening tool rather than definitive assessment.
  • Collect first morning urine for most consistent results. Avoid iodine supplements for 3 days before testing. Follow kit instructions for proper collection and shipping.
  • Yes, spot urine can track whether supplementation is affecting your iodine intake, though the loading test better shows whether tissue stores are being replenished.

How to prepare

Discontinue iodine supplements for 3 days before testing. Collect first morning urine sample for most consistent results. Avoid high-iodine foods (seaweed, excessive iodized salt) for 24 hours before collection. Follow kit instructions for proper sample collection and shipping.

After the test

Address low urinary iodine through increased consumption of iodine-rich foods or appropriate supplementation under healthcare guidance. Monitor high levels by identifying and reducing excessive iodine sources. Consider thyroid function testing for comprehensive assessment.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Results show urinary iodine concentration compared to WHO reference ranges. Levels below 100 μg/L may indicate inadequate iodine intake requiring dietary changes or supplementation. Levels above 300 μg/L may suggest excessive intake needing reduction.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"
