What This Panel Measures

Muscle & nerve function. Magnesium keeps muscles and nerves firing normally; low levels can cause cramps and twitching.
🫀
Heart rhythm. Magnesium supports a steady heartbeat, and deficiency can contribute to palpitations.

  • You take medications that lower magnesium (some diuretics, acid reducers)
  • You have type 2 diabetes or gut conditions that affect absorption
  • You drink alcohol regularly

Understanding Your Results

Results post to your secure online account usually in 1–2 business days, with your value and the normal range. Blood magnesium reflects only a small fraction of the body's total, so a normal result doesn't always rule out a mild deficiency. Symptoms and repeat testing help interpret borderline values.

Frequently Asked Questions

Do I need to fast?
No fasting is required — you can test any time of day.
Can I take my magnesium supplement before the test?
It's best to take supplements as usual but not right before the draw, so your result reflects your typical level rather than a recent dose.
Is this billed to insurance?
No — you pay directly here, and nothing appears on your insurance record. Results go only to your secure account.
