What's this test for?

This test is ideal if you're experiencing symptoms like fatigue, headaches, numbness, or trouble concentrating and you suspect mercury exposure from your diet, water, workplace, or dental work. It's also useful if you eat a lot of fish or work in an industry that uses mercury and want to check your exposure level. This test measures mercury inside your red blood cells, which reflects exposure over the past few months.

What happens after I get my results?

Your results will show up in your account with the normal reference range clearly explained so you can see exactly where your level falls. If your mercury level is elevated, simple next steps include reducing high-mercury fish intake, identifying and removing other exposure sources, and retesting in a few months to confirm the level is coming down. If your result is very high, seek medical care right away. You can download a standard lab report anytime and use the trends feature to track your mercury level over time if you retest.

Who should consider this test?

Anyone who regularly eats large predatory fish like tuna, swordfish, or shark should consider this test, since these foods are a common source of mercury exposure. People who work with mercury-containing products, such as dental staff, industrial workers, or those handling old thermometers or fluorescent bulbs, are also good candidates. It's also worth checking if you've had unexplained fatigue, tingling, or memory issues that haven't been explained by other causes.

What symptoms indicate I may need this test?

Common symptoms linked to mercury exposure include fatigue, headaches, numbness or tingling in the hands and feet, memory or concentration problems, and muscle weakness. Some people also notice mood changes, tremors, or vision and hearing changes with higher exposure. If you have several of these symptoms and a possible source of mercury exposure, this test can help clarify what's going on.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be posted directly to your online account, where you can view and download them at your convenience. You'll get a notification as soon as your report is ready to view.

How can I naturally lower my mercury exposure?

Cutting back on high-mercury fish like swordfish, king mackerel, and tuna is one of the most effective steps you can take. Choosing lower-mercury seafood like salmon, shrimp, and sardines instead still lets you get healthy omega-3s without as much risk. Making sure you're getting enough fiber, selenium, and antioxidants through foods like leafy greens, nuts, and berries can also support your body's natural detox processes. Drinking plenty of water and avoiding other sources of mercury, like certain old thermometers or skin creams, rounds out a practical approach.

What does a high mercury result mean?

A high result means you have more mercury built up in your red blood cells than is typically seen in people without significant exposure. This usually points to ongoing intake from sources like fish, dental work, or occupational contact, rather than a one-time exposure. The higher the number, the more important it is to identify and remove the source and retest to track your progress.

What causes elevated mercury levels?

The most common cause is regularly eating fish that are high in mercury, especially larger predatory species. Occupational exposure, such as working with mercury in dental offices, manufacturing, or mining, is another major cause. Less commonly, exposure can come from certain skin-lightening creams, old medical devices, or environmental contamination in water or air.

How often should I retest?

If your first result comes back elevated, retesting every 2-3 months after making changes to your diet or environment is a reasonable approach to track improvement. If your level is within the normal range and you don't have ongoing exposure risks, annual testing or testing only when new symptoms appear is usually enough. Anyone with a known ongoing exposure source should retest more frequently until levels come down.

What should I do if my results are abnormal?

Start by looking at your recent diet and environment to identify likely sources, such as high-mercury fish or exposure at work. Reduce or eliminate that source right away and retest in a few months to see if your level is dropping. If your result is very high or you have serious symptoms like severe numbness, confusion, or tremors, seek medical care immediately.
