Measure the levels of magnesium in your blood that can help detect conditions such as preeclampsia, or conditions affecting kidney or intestine function.
This test measures the level of magnesium in your blood. Magnesium is an important electrolyte and mineral that plays a vital role in many bodily functions. Low levels can indicate various health issues, including kidney or intestine problems. This test helps detect such deficiencies early, allowing for timely intervention and treatment. It's particularly useful for monitoring conditions like preeclampsia in pregnant women.

Who Is This For?
Vegetarians and vegans (at higher risk of B12, iron, and zinc deficiency). Older adults, as nutrient absorption decreases with age.

Athletes with high nutrient demands from training.

Biomarkers Tested
3Involved in over 300 enzymatic reactions including energy production, muscle function, and nerve signaling. Magnesium deficiency is common and associated with muscle cramps, anxiety, insomnia, and increased cardiovascular risk.
Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.
Essential for DNA synthesis, cell division, and red blood cell formation. Folate deficiency causes megaloblastic anemia and, during pregnancy, increases the risk of neural tube defects. Works closely with vitamin B12.
