Which test assesses blood magnesium levels?

The test that specifically assesses blood magnesium levels is the Magnesium (Mg) test. This test measures the concentration of magnesium in the blood, which is essential for various bodily functions, including nerve impulse transmission, muscle contraction, and maintaining a stable heart rhythm. Magnesium is also crucial for many biochemical reactions in the body, including energy production and the synthesis of DNA and protein.

Regular monitoring of magnesium levels can help detect deficiencies or excesses that may lead to health issues such as muscle cramps, weakness, or cardiovascular problems. Since the other tests—sodium, iron panel, and uric acid—are designed to assess different substances in the blood, they do not provide information specifically related to magnesium levels.
