What's this test for?

This test is ideal if your child has symptoms that could point to low magnesium, like muscle cramps, weakness, irregular heartbeat, or fatigue. Urine magnesium can drop before blood levels change, so this test can catch a problem earlier than a standard blood test might. It's often used when a child has ongoing symptoms but earlier blood work looked normal.

What happens after I get my results?

Your child's results will show up in your account with the normal range clearly marked so you can see exactly where the magnesium level falls. If the level is outside the normal range, simple next steps include adjusting magnesium-rich foods in the diet, discussing supplementation, or retesting in a few weeks to check progress. If the result shows a very low level along with symptoms like irregular heartbeat, seek medical care right away. You can download the full lab report from your account anytime, and the trends feature lets you track magnesium levels over multiple tests.

Who should consider this test?

Parents whose child has muscle cramps, weakness, fatigue, or an irregular heartbeat that hasn't been explained may want to consider this test. It's also useful for kids with digestive conditions, poor appetite, or those on medications that can affect mineral levels. Because urine magnesium can signal a problem before blood levels change, it's a good early-detection option.

What symptoms indicate I may need this test?

Watch for muscle cramps, twitching, weakness, tiredness, poor appetite, nausea, or an irregular heartbeat in your child. Trouble sleeping and mood changes can sometimes be linked to low magnesium too. If these symptoms show up and blood tests haven't found a clear answer, this urine test may give more insight.

How can I naturally support healthy magnesium levels?

Offer magnesium-rich foods like leafy greens, nuts, seeds, whole grains, and bananas as part of regular meals. Staying hydrated and limiting sugary drinks can also help the body keep minerals balanced. If a supplement seems needed, start with food sources first and use the retest option to see if levels improve before adding anything extra.

When will I get my results?

Results are typically ready within about 7 days of the lab receiving the sample. You'll get a notification as soon as your results are posted to your account, where you can view and download the full report.

What does low magnesium mean?

A low urine magnesium result can mean the body isn't getting enough magnesium from food, isn't absorbing it well, or is losing too much through urine. This can sometimes explain symptoms like cramping, weakness, or heart rhythm changes. Simple dietary changes are often the first step, with retesting to confirm improvement.

What causes low urine magnesium?

Common causes include a diet low in magnesium-rich foods, digestive issues that affect nutrient absorption, certain medications, or excessive fluid loss from vomiting or diarrhea. Some kids naturally process magnesium differently, especially during growth spurts. Identifying the cause often starts with reviewing diet and recent health history.

How often should I retest?

If a first result comes back low or symptoms continue, retesting in 4-6 weeks after making dietary changes is a reasonable starting point. If levels are healthy and there are no symptoms, retesting usually isn't needed unless new symptoms appear. Tracking results over time in your account can help you see patterns.

What should I do if my results are abnormal?

Start by reviewing your child's diet for magnesium-rich foods and consider small changes like adding more leafy greens, nuts, or whole grains. Keep an eye on symptoms like muscle cramps or irregular heartbeat, and if these are severe or worsening, seek medical care promptly. Retesting after a few weeks of changes can help confirm whether the levels have improved.
