What's this test for?

This test is ideal if you're experiencing unexplained fatigue, weight changes, or thyroid concerns that might be linked to your diet. Iodine is a nutrient your body needs to make thyroid hormones, and too little or too much can throw things off. This test helps you see if your iodine intake is in a healthy range.

How should I prepare for this test?

How can I naturally support healthy iodine levels? Eating iodine-rich foods like seaweed, dairy, eggs, and iodized salt can help keep your levels balanced. If your levels run high, cutting back on iodine supplements or iodine-heavy foods for a while can help bring things back down naturally. Staying consistent with your diet in the weeks before testing gives you the most accurate picture of your usual intake.

What happens after I get my results?

Your results will show up in your account with your iodine level and an explanation of what counts as a normal range. If your level is off, the report offers simple next steps, like adjusting iodine-rich foods in your diet or considering a retest in a few months to check progress. You can download a standard lab report anytime from your account, and if you test again later, the trends feature lets you track your iodine levels over time.

When will I get my results?
Results are typically ready within about 7 days after your sample is processed at the lab. You'll get a notification once they're posted to your account so you can log in and review them right away. This timeframe gives the lab enough time to run an accurate analysis of your urine sample.
Who should consider this test?
This test is a good fit for anyone who suspects their diet might be too low or too high in iodine, especially people with thyroid symptoms like fatigue, weight changes, or neck swelling. It's also useful for people who eat a lot of processed food, avoid dairy and seafood, or use iodized salt substitutes. If you've had thyroid issues in the past or are curious about your nutrient intake, this test can offer useful insight.
What symptoms indicate I may need this test?
Symptoms like unexplained tiredness, weight gain or loss, feeling unusually cold, dry skin, or swelling in the neck area can all be linked to iodine imbalances. Hair thinning and brain fog are other signs worth paying attention to. If these symptoms sound familiar, checking your iodine level is a reasonable first step.
What is iodine and why does it matter?
Iodine is a mineral your body needs in small amounts to make thyroid hormones, which control your metabolism, energy, and body temperature. Without enough iodine, your thyroid can't work properly, which can lead to fatigue, weight changes, and other symptoms. Getting the right amount, not too little or too much, keeps your thyroid running smoothly.
What does high iodine mean?
A high iodine result can mean you're getting more than your body needs, often from supplements, iodized salt, or certain foods like seaweed. In some cases, too much iodine can actually cause thyroid problems similar to having too little. Cutting back on iodine-rich supplements and foods, then retesting in a few months, is a reasonable next step.
What does low iodine mean?
A low result suggests your diet may not include enough iodine-rich foods, which can affect how well your thyroid makes hormones over time. Adding foods like iodized salt, dairy, eggs, and seafood can help raise your levels naturally. If symptoms like fatigue or weight changes continue after adjusting your diet, retesting can help you see if your levels have improved.
How often should I retest?
If you're making diet changes to correct a high or low result, retesting after 2-3 months is a good way to see if those changes are working. If your levels are normal and you have no symptoms, an annual check is usually enough. People with ongoing thyroid symptoms may want to test more frequently to keep an eye on things.
