Service Description

Magnesium RBC Test Specimen Type: Blood | Fasting: Not required | Results: About 4 business days What It Is This test looks at the magnesium stored inside your red blood cells, which gives a longer-term view than a standard serum test. This test includes: • Magnesium, RBC (red blood cell) Most of your magnesium lives inside cells, not in the blood fluid, so a serum level can look normal while your stores run low. Low magnesium can show up as muscle cramps, twitching, poor sleep, anxiety, or fatigue. Who It's For This test is a good fit for: • Anyone with cramps, twitching, poor sleep, or fatigue • People taking diuretics or acid reflux medicine long term • Anyone whose serum magnesium looked normal but symptoms continue • Anyone working with a nutrition or functional medicine provider Just need a quick check? Our serum Magnesium Test is faster and doesn't require stopping supplements. What to Expect Preparation: Important: stop all vitamins, minerals, and herbal supplements for one full week before this test, unless your provider tells you otherwise. Taking them can make your result inaccurate. No fasting needed. Your Visit: A fast, 15-minute blood draw at Quick Test Health Services of Tucson, right off the I-10 close to downtown.
