What's this test for?

This test is ideal if you're experiencing unexplained fatigue, muscle weakness, poor recovery from exercise, or suspect you might have nutritional deficiencies. It measures essential minerals directly inside your red blood cells, which gives a more accurate picture of your body's mineral stores than standard blood tests. Many people use this test when they want to optimize their nutrition, address persistent tiredness, or ensure they're absorbing minerals properly from their diet.

How should I prepare for this test?

For the most accurate results, it's best to fast for 8-12 hours before your blood draw, though water is allowed. Avoid taking mineral supplements for at least 24 hours before the test, as they can temporarily elevate levels and affect accuracy. If you take prescription medications, continue them as normal unless your doctor advises otherwise, and be sure to inform the lab of any supplements you're currently taking.

What's included in this test?

Mineral Profile, RBCs

This comprehensive panel measures essential minerals directly within your red blood cells, including magnesium, zinc, copper, selenium, and other trace minerals that are critical for energy production, immune function, and overall health. Testing minerals in red blood cells provides a more accurate assessment of your long-term mineral status compared to standard serum tests, as it reflects what's actually stored and available for your body to use. Together, these measurements help identify deficiencies or imbalances that may be contributing to fatigue, poor recovery, weakened immunity, or other health concerns.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your mineral levels mean for your energy, muscle function, and overall health. These notes include personalized recommendations like dietary changes, specific mineral supplements to consider, or whether certain levels need closer monitoring. You'll also get the standard lab report and can track your mineral levels over time using our trends feature to see how your dietary changes or supplements are working.
Who should consider getting this test?
This test is valuable for anyone experiencing chronic fatigue, athletes wanting to optimize performance, people with digestive issues that might affect nutrient absorption, or those following restrictive diets that could lead to mineral deficiencies. It's also helpful for individuals taking medications that deplete minerals, people with chronic stress, or anyone who wants to ensure their body has adequate mineral stores for optimal health and energy.
What symptoms indicate I may need this test?
Common symptoms of mineral imbalances include persistent fatigue that doesn't improve with rest, muscle cramps or weakness, poor exercise recovery, brain fog or difficulty concentrating, weakened immunity with frequent illnesses, and changes in hair or skin quality. You might also experience mood changes, irregular heartbeat, or general feelings of being run down despite eating well. If you have several of these symptoms, checking your mineral levels can help identify the root cause.
How can I naturally support my mineral levels?
Focus on eating a varied, whole-foods diet rich in colorful vegetables, nuts, seeds, lean proteins, and whole grains, as different minerals come from different food sources. Foods like leafy greens provide magnesium, shellfish and beef are rich in zinc, Brazil nuts contain selenium, and pumpkin seeds offer multiple minerals. Avoid excessive caffeine and alcohol, which can deplete minerals, and consider reducing processed foods that lack nutritional value. Managing stress and ensuring good sleep also helps your body absorb and utilize minerals more effectively.
What is red blood cell mineral testing and why does it matter?
Red blood cell (RBC) mineral testing measures minerals stored inside your red blood cells rather than in your serum (the liquid part of blood). This matters because RBC testing reflects your mineral status over the past 3-4 months, giving a much more accurate picture of long-term mineral stores than standard blood tests. Serum levels can fluctuate based on what you ate recently, but RBC levels show what your body has actually absorbed and stored for use in critical functions like energy production, enzyme activity, and cellular health.
What does low mineral levels mean?
Low mineral levels in red blood cells indicate that your body doesn't have adequate stores of essential minerals for optimal function. This can result from poor dietary intake, digestive issues that prevent proper absorption, chronic stress that depletes minerals, or increased demands from exercise or illness. Low levels can affect energy production, immune function, muscle performance, and many other body processes. The good news is that most mineral deficiencies can be corrected through targeted dietary changes and supplementation.
How often should I retest my mineral levels?
If you're addressing a mineral deficiency with diet changes or supplements, retesting in 3-4 months is ideal to see if your levels have improved and ensure you're on the right track. Once your levels are optimized, annual testing is usually sufficient for maintenance monitoring. However, if you have ongoing digestive issues, are under significant stress, or make major dietary changes, you may want to test more frequently to ensure your body is maintaining adequate mineral stores.

What this means

Your red blood cell magnesium level is slightly below the optimal range. While not severely deficient, this may contribute to muscle cramps, fatigue, poor sleep quality, or difficulty managing stress. Low magnesium is common and can affect energy production, muscle function, and nervous system health.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
