Red Blood Cell Magnesium (RBC Magnesium) Blood Test

$115.00 AUD

Experiencing muscle cramps, fatigue, or anxiety and want the most accurate assessment of your magnesium status and cellular mineral levels?

The Red Blood Cell Magnesium Blood Test measures magnesium stored inside red blood cells, giving a more accurate picture of long-term magnesium status than a standard blood test. Magnesium is vital for energy, muscle function, heart rhythm, and nerve health. Low levels may cause cramps, fatigue, or heart problems.

This test is only available at Healius collection centres.

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.

"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

The RBC Magnesium test is like having a detective that can peek inside your cells to see what's really happening with your magnesium levels. While standard blood tests only check magnesium floating around in your bloodstream, this test looks directly inside your red blood cells where magnesium actually does its important work – think of it as checking your body's actual magnesium savings account rather than just the pocket change. This gives you a much more accurate picture of whether your cells have enough of this vital mineral to keep everything running smoothly.

Magnesium acts like your body's multi-tool, helping with over 300 different jobs including producing energy, keeping your muscles and nerves working properly, and maintaining steady blood sugar and blood pressure. When your cellular magnesium runs low, you might experience muscle cramps, fatigue, anxiety, sleep troubles, or even irregular heartbeats – but here's the tricky part: regular blood tests might still show "normal" levels because your body prioritizes keeping magnesium in your bloodstream, even if it means robbing your cells. The RBC Magnesium test catches this hidden deficiency, making it especially valuable if you're dealing with unexplained symptoms, have conditions like diabetes that increase magnesium needs, or want to make sure your magnesium supplements are actually reaching your cells where they're needed most.

Symptoms

Essential for individuals with muscle cramps, fatigue, suspected magnesium deficiency, or anyone needing accurate intracellular magnesium assessment.

Questions

  • RBC magnesium better reflects tissue stores and functional magnesium status, as serum levels can appear normal even when cellular magnesium is deficient.
  • Signs include muscle cramps, fatigue, anxiety, sleep problems, irregular heartbeat, headaches, and poor stress tolerance, though deficiency can be subtle.
  • Causes include poor dietary intake, gastrointestinal disorders, diabetes, kidney disease, certain medications, chronic stress, and increased magnesium needs.
  • Daily requirements vary but generally range from 300-400mg for adults, with higher needs during pregnancy, illness, stress, or intense physical activity.
  • Good sources include leafy greens, nuts, seeds, whole grains, legumes, dark chocolate, and certain fish like mackerel and salmon.
  • Cellular magnesium repletion can take several months of consistent supplementation, which is why RBC testing is valuable for monitoring progress.

How to prepare

No special preparation required. Inform healthcare provider of all magnesium supplements and medications that might affect magnesium levels. Consider timing relative to recent supplementation.

After the test

Address low RBC magnesium through appropriate magnesium supplementation, dietary improvements, addressing underlying absorption issues, and regular monitoring to achieve optimal cellular levels.

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 RBC magnesium levels compared to optimal ranges. Low levels indicate cellular magnesium deficiency requiring supplementation, while optimal levels suggest adequate intracellular magnesium status.

Frequently Asked Questions

Most collection centres accept walk-ins. Some may require a booking - check details when you click on your chosen location.

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.

Just your pathology referral form (we email it to you)

Of course. Just maybe don’t bring the friend who faints at the sight of blood.
