Want a simple, convenient way to assess your iodine status and determine whether your recent iodine intake is adequate for optimal thyroid function and health?
The Iodine Random Urine Test measures how much iodine is in your urine. Iodine is essential for making thyroid hormones, which control metabolism, energy, and growth. This test may help check if you’re getting enough iodine from your diet or if thyroid-related symptoms could be linked to low or high iodine levels.

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.

Calcium Blood Test
"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"

Overview
Think of random urine iodine testing as checking what your body is releasing through your kidneys, like examining the exhaust from your car to understand how efficiently your engine is running. Your kidneys act as smart regulators, holding onto iodine when you're running low and releasing excess when you have plenty, so this simple urine test reveals whether your body is getting enough of this essential nutrient. Iodine is like fuel for your thyroid gland, which acts as your body's master control center for metabolism, energy levels, and body temperature.
This convenient test requires just a single urine sample and reflects your iodine intake over the past few days to weeks, making it an excellent way to assess whether your diet is meeting your body's needs. Since iodine deficiency has become surprisingly common due to reduced salt intake and increased consumption of processed foods, this test helps identify if you might benefit from dietary changes or supplements before any thyroid problems develop. Unlike blood tests that show what's currently in your system, urine testing reveals what your body is actually doing with the iodine you consume - giving you valuable insights into your overall iodine status and thyroid health.
Symptoms
Essential for individuals wanting to screen for iodine deficiency, those with thyroid concerns, people following restrictive diets, or anyone seeking a convenient assessment of their iodine status.
Questions
Random urine testing provides good screening information about iodine status, though 24-hour collections are more precise. For most people, random testing is sufficient for initial assessment.
Yes, first morning urine typically provides the most consistent results as it represents overnight concentration. Avoid testing immediately after meals high in iodine.
Avoid seaweed, iodized salt, seafood, dairy products, and iodine supplements for 24-48 hours before testing for most accurate baseline assessment.
Urine iodine reflects recent intake and helps assess whether you're consuming enough iodine for optimal thyroid hormone production, though thyroid function tests are needed for complete evaluation.
Yes, iodine-containing medications, contrast agents, antiseptics, and some supplements can significantly elevate urine iodine levels. Inform your healthcare provider of all medications.
For screening, once annually or as recommended by your healthcare provider. More frequent testing may be needed if you're addressing deficiency or monitoring supplementation.

How to prepare
Provide first morning urine sample for most accurate results. Discontinue iodine supplements for 3 days before testing. Avoid high-iodine foods (seaweed, iodized salt) for 24 hours before collection. Collect urine sample at laboratory facility according to instructions.
After the test
Address low urinary iodine through increased consumption of iodine-rich foods or appropriate supplementation. Monitor high levels by reducing iodine intake sources. Consider follow-up testing and thyroid function assessment for comprehensive evaluation.
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. Levels above 300 μg/L may suggest excessive intake. Results guide dietary modifications or supplementation recommendations.
